Where the above rectangle has the given dimensions, this means that:
m∠1 = 49°
m∠2 = 41°
m∠3 = 41°
∠ADC = 90°
AB = 7.5
BD = 10
CE = 5
What are the properties of a rectangle?The following are the qualities of a rectangle:
A quadrilateral with four equal internal angles is known as a rectangle.A rectangle's opposite sides are equal and parallel to one other.A rectangle's inner angle at each vertex is 90°.The sum of a rectangle's internal angles equals 360°.The diagonals cut each other in half.The diagonals are all the same length.The Pythagorean theorem may be used to calculate the length of the diagonals. (a2 + b2) is the length of the diagonal with sides a and b.A rectangle is sometimes known as a parallelogram because its sides are parallel.Parallelograms are all rectangles, but rectangles are not all parallelograms.1) Since the diagonals cut one other in half, it means that ΔCEB, ΔAED are congruent isosceles triangles. It also means that ΔAEB and ΔDEC are congruent isosceles triangles.
This means that ∠BCE = ∠CEB
Where ∠AEB = 98°
∠ABE = (180-98)/2
= 41°
Thus, m∠1 = 90- 41°
m∠1= 49°
2 and 3) Given that ΔAEB and ΔDEC are congruent isosceles triangles, and ∠AEB and ∠DEC are opposite angles (which are congruent), that means
∠AEB and ∠DEC = 98°
Thus,
m∠2 and m∠3 = (180-98)/2 that is
m∠2 and m∠3 = 41° respectively.
4) ∠ADC = 90° (Property of a rectangle)
5) Given an angle and the hypotenuse, we can find AB. Using the law of sines that is:
AB = AC * Sin ∠DAC
Note that ∠DAC ≅ ∠1
Note that AC = 10 (properties of a Rectangle)
Thus
AB = 10 * Sin 49°
AB = 10 * 0.75470958022
AB = 7.5470958022

Step-by-step explanation:
An equilateral triangle is one in which all three sides are congruent. It also has the property that all three interior angles are equal. In other words, all three angles of an equilateral triangle are always 60°.
So ∠ABE = 90+60=150.
because ABCD is square so AB = BC
because BEC is equilateral triangle, so BC = BE = AB
so we know in ABE triangle the 2 sharp angles are the same
so ∠AEB = (1/2) * (180-150) = 15
so ∠DAE = 90-15 =75

How do you find m1 and m2 in coordinate geometry?
In coordinate geometry, the slope of a line, m, is defined as the ratio of the change in y to the change in x of any two distinct points on the line. It can also be written as the ratio of the rise to the run.
What is meant by coordinate geometry?
Coordinate geometry (or analytic geometry) is defined as the study of geometry using the coordinate points. Using coordinate geometry, it is possible to find the distance between two points, dividing lines in m:n ratio, finding the mid-point of a line, calculating the area of a triangle in the Cartesian plane, etc.
To find the slope of a line, we can use the two-point form of the equation of a line, which is:
y = mx + b
Where m is the slope and b is the y-intercept.
To find the slope, we can use any two distinct points (x1, y1) and (x2, y2) on the line. To find m1 and m2, we use the following formulas:
m1 = (y2-y1) / (x2-x1)
m2 = (x2-x1) / (y2-y1)
It is important to note that m1 and m2 are the same value, just in different forms. m1 is the slope and m2 is the reciprocal of the slope.
In cases when x2-x1=0 (parallel to y-axis) or y2-y1=0(parallel to x-axis) the slope would be undefined and undefined respectively.

What are the 2 most common errors that people make when creating while loops?
The two most common errors that people make when creating while loops are infinite loops and off-by-one errors.
What is error in math?Error in math is when an incorrect result is obtained from a mathematical calculation. It can be caused by a mistake made in the calculation (such as a wrong formula or an incorrect use of a calculator) or by a misunderstanding of the problem being solved. Error in math can also be caused by a wrong assumption about the data being used. Regardless of the cause, an error in math can have serious consequences, as incorrect results can lead to incorrect decisions and actions.
An infinite loop is when a while loop is created that never ends, as the condition that the loop checks for never becomes false. An off-by-one error is when the loop is written in such a way that the loop will run one iteration too many or too few. This can lead to incorrect results and cause the loop to miss or repeat certain parts of the loop. To prevent these errors, it is important to have a clear understanding of the loop's condition and to always test the loop thoroughly before using it.

here is a long division calculation of 917 ÷ 7 in words, explain the steps used to solve.
Step-by-step explanation:
Step 1: Create a division problem with the numbers being divided lined up one above the other.
Step 2: Divide the first digit of the dividend (917) by the divisor (7), and write the quotient (130) above the dividend.
Step 3: Multiply the divisor (7) by the quotient (130) and write the product (910) below the dividend (917).
Step 4: Subtract the product (910) from the dividend (917) and write the difference (7) below the product.
Step 5: Bring down the next digit of the dividend (917), making the next number to divide (7).
Step 6: Divide the new number by the divisor, and write the quotient, this case 0 (since 7 doesn't divides into 7) above it, and add the remainder, which is still 7.
Step 7: The remainder is the final result of the division. 917 divided by 7 is 130 with a remainder of 7, so the final answer is 130 remainder 7, this can be represented as 130 R 7.
Note: Even though it is not shown in the explanation above, to check the solution is correct, you could also multiply the quotient (130) by the divisor (7) and add the remainder (7) to get back to the dividend (917)
It's also worth to note that the final remainder could be seen as the number we couldn't divide and the quotient as the result of the division.

Step-by-step explanation:
Arun is driving on a long road trip. He currently has 9 gallons of gas in his car. Each
hour that he drives, his car uses up 1 gallon of gas. How much gas would be in the
tank after driving for 5 hours? How much gas would be left after t hours?
Gas left after 5 hours:
Gas left after t hours:
Please hurry
Answer:
9
Step-by-step explanation:
After driving for 5 hours, Arun's car would have used up 5 gallons of gas (1 gallon per hour for 5 hours). Therefore, the amount of gas left in the tank after driving for 5 hours would be 9 gallons - 5 gallons = 4 gallons.
To find the amount of gas left after t hours, we can use the formula:
Gas left after t hours = 9 - (1 x t)
Where t is the number of hours driven.
So, the amount of gas left after t hours would be 9 - t gallons.
After driving for 5 hours, Arun would have 4 gallons of gas left in his tank. If he drives for t hours, he would have (9 - t) gallons of gas left in his tank. The calculations are based on the fact that Arun's car uses 1 gallon of gas per hour of driving.
Explanation:To answer this question, we must understand that Arun's car uses 1 gallon of gas for every hour of driving. So, if he drives for 5 hours, his car will use 5 gallons of gas. Arun starts with 9 gallons of gas, so we subtract the 5 gallons of gas used from the 9 gallons of gas he started with. The result is:
9 - 5 = 4 gallons
So, after driving for 5 hours, Arun would have 4 gallons of gas left in his tank.
Similarly, if he drives for t hours, his car will use t gallons of gas. So, to find how much gas would be left after driving for t hours, we subtract t gallons from the 9 gallons he started with:
