Answer:

45

Step-by-step explanation:

If sam made a rectangle 9 feet in length and 15 in width. And we already know the next rectangle is 27 feet we can divide it by 9.

27/9=3

Now that we know its 3x the normal size we can grab the 15 and multiply it by 3.

15x3=45

Answer:

39°

Step-by-step explanation:

You would do 39+102 Which equals 141°

Because a triangle has 180° in it you would then do 180-141 which is 39°

Answer: The answer is 39

Step-by-step explanation:

39 + 102 = 141

180 - 141 = 39

Answer:

= $655.20

Step-by-step explanation:

Simple Interest =( Principal * rate * time)/100

                          =( $ 6300 * 2.60% * 4years)/100, workout in the brackets first then divide by 100.

                        =   65520/100

                        = $655.20

Dexter will earn $655.2.

Simple interest is the borrowing amount added only to the principal amount.

Formula to calculate the simple interest is;

                                                 S.I. = P x T x R / 100 ,

Where S.I. is simple interest , P is principal amount, T is time period and R is interest rate in a year.

Dexter deposited $6,300 into a savings account that earns 2.60% simple interest per year.

P = $6300

R = 2.60% and T = 4 years

Then by the formula;

6300 x 2.6 x 4 /100

= $655.2

Therefore, Dexter will earn $655.2.

Answer:

Step-by-step explanation:

Supplementary angles have a sum of 90 degrees.

a+52=90

a=90-52

a=38 degrees

The equation equivalent to the Amil equation is (x + 7)² - 12 = 0 thus option (A) is correct.

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.

A formula known as an equation uses the same sign to denote the equality of two expressions.

As per the given Amil equation,

x² + 14x + 37 = 0

Add 12 on both sides,

x² + 14x + 37 + 12 = 0 + 12

x² + 14x + 49 = 12

(x + 7)² = 12

(x + 7)² - 12 = 0

Hence "(x + 7)² - 12 = 0 represents the Amil equation's equivalent".

Step-by-step explanation:

Answer:

The answer is that angle 1 is 70 degrees.

Step-by-step explanation:

Alright so all vertical angles are congruent and the sum of all angles IN and triangle equals 180 degrees. So, the angle on the inside of the top of the triangle is 60 degrees because vertical angles are congruent. Now the angle across from the 130 degree angle is 130 degrees, and we know that the outer and inner angles are supplementary, (add up to 180 degrees) so the angle on the inside is 50 degrees. Then, all angles of a triangle equal 180 degrees therefore, 180-(60+50)= the final angle. Now 70 degrees is the last angle and this angle is vertical to angle 1 which means that angle 1 equals 70 degrees.

Answer:

angle 4 = angle 2{opposite angles are equal} =45 degrees

Step-by-step explanation:

Answer:

Step-by-step explanation:

Angle 4 is an exterior angle which corresponds to the remote interior angles of 33 degrees and 75 degrees. Through the remote interior angle theorem, we can add the remote interior angles to get the exterior angle So we simply add 33 and 75 to get 33+75 = 108 If you chose not to use this theorem, then you can find angle three by using the fact that all three angles of the triangle must add to 180 degrees. So, 33+75+(angle 3) = 180 108+(angle 3) = 180 108+(angle 3) - 108 = 180 - 108 angle 3 = 72 degrees Then use the fact that angle 3 and angle 4 are supplementary (angle 3) + (angle 4) = 180 72 + (angle 4) = 180 72 + (angle 4) - 72 = 180 - 72 angle 4 = 108 degrees either way, we get the same answ
