Question

13.
Find the measure of ZC.
A
36°
B

Answer 1

C = 72

Explanation:

Angle C and <B are the same since it is an isosceles triangle and the base angles are the same measure

A + B+ C = 180 since the angles of a triangle add to 180

36 + C + C = 180

Combine like terms

36+ 2C =180

Subtract 36 from each side

36 -36+ 2C =180-36

2C =144

Divide by 2

2C/2 =144/2

C =72
