Question 9 10 pts
The perimeter of a triangle is 30 inches. After a dilation, the perimeter is 6
inches. What is the scale factor of the perimeter?
Write your answer like this: Write the scale factor as a fraction: a/b

c. 65°

step-by-step explanation:

we are given a triangle with two known angles, 62° and 53°, while the third angle x is unknown and we are to find its value.

we know that the sum of angles in a triangle is equal to a total of 180 degrees. so we can write it as:

x + 62° + 53° = 180°

solving to find the value of x:

x = 180 - (62 + 53) = 65°

therefore, the value of x in this triangle is 65°.
