Answer:
48 degree
Step-by-step explanation:
Angle EFD=Angle EGD=42 degree
Angle EFG=90 degree
Angle DFG=Angle EFG- Angle EFD=90 degree-42 degree=47 degree
Answer:
m∠DFG = 48°
Step-by-step explanation:
Angles in a semicircle Theorem
The angle at the circumference in a semicircle is 90°
Therefore, if EOG is the diameter of the circle, then
m∠EDG and m∠EFG are both 90°
As the sum of the interior angles of a triangle is 180°
m∠EDG + m∠EGD + m∠DEG = 180°
⇒ 90° + 42° + m∠DEG = 180°
⇒ m∠DEG = 48°
As the angles at the circumference subtended by the same arc are equal, (i.e. angles in the same segment are equal) then
m∠DFG = m∠DEG = 48°

This is Right Angled Triangle.⠀
We'll solve this using the Pythagorean Theorem.
Let,
x be AC, where AC is the Hypotenuse.4 be AB, where AB is the Perpendicular.8 be BC, where BC is the Base⠀
We know that,
[tex]{ \longrightarrow \pmb{ \qquad (AC) {}^{2} = (AB) {}^{2} +( BC) {}^{2} }}[/tex]

If two angles are supplementary and congruent, what is the measure of each angle?
100°
180°
90°
45°
Answers
Answer:
90
Step-by-step explanation:
supplementary angles equal 180 degrees and 90+90=180
Answer:
90°
Step-by-step explanation:
Supplementary angles are angles that add up to 180°.
Congruent means the angles are equal to each other.
Since there are two angles, and they have to be equal to each other, we can divide 180° by 2 to find the measure of each angle.
180° / 2 = 90°
Both angles have a measure of 90°.

Answers
The total amount it would cost to make 110 bon bons given the cost per gram is $24.52.
What is the total amount it would cost to make 110 bon bons?The first step is to determine the gram used in making the chocolate.
Gram = density x volume
Volume = 4/3πr³
4/3 x 22/7 x (2/2)³ = 4.19cm³
Gram = 4.19cm³ x 1.33 = 5.57 g

a. Juan says that the factory can make 5 batches of marbles with
the 10 pounds of dye. Explain why his statement is not reasonable.
Answers
Answer:
10 ÷ 0.2=50
Step-by-step explanation:
10 lbs in total. Each batch uses 0.2 lbs.
We can find how many batches can be made by dividing 10 by 0.2.
10 ÷ 0.2=50
Juan is incorrect because if they could only make 5 batches then they would have only had 1 pound of red dye available.
They have 10 pounds of red dye available to make marbles, and if each batch takes only 0.2 lbs of it, then they can make 50 batches of marbles.

One side of a triangle is 5 units longer than a second side. The ray bisecting the angle formed by these sides divides the opposite side into segments that are 7 units and 9 units long. Find the perimeter of the triangle. Give your answer as a reduced fraction or exact decimal
Please explain your answer.
Answers
The perimeter of the triangle described in statement has a measure of 56 units long.
How to determine the perimeter of a triangle
After a quick though careful reading, we construct a triangle based on all information given in the statement, based on the fact that the longest segment is adjacent to the longest missing side. Since both sides have two angles with the same magnitude, then we have the following ratios:
[tex]\frac{x}{7} = \frac{x+5}{9}[/tex] (1)
Now we solve the expression for x:
9 · x = 7 · x + 35
2 · x = 35
x = 17.5
And the perimeter of the triangle is determine by summing the three sides:
p = 9 + 7 + (17.5) + (17.5 + 5)
p = 56
The perimeter of the triangle described in statement has a measure of 56 units long. [tex]\blacksquare[/tex]

Answers
Let’s take x = -5 + 7 for example.
First, we need to remove -5. We can do this by adding 5 to -5 to make it zero. Since we added 5, we have to add 5 to seven. What ever you do on one side, you have to do to the other. 5 + 7 = 12. Now all that’s left on the equation is x = 12 and that would be your answer. Im not good at explaining things but I hope this helps you!
