Question

ZC and ZD are vertical angles with mZC = -x + 26 and mZD = 2x – 10.

What is mZD?
Enter your answer in the box.

Answer 1

mZD=62

Explanation:

mZC=-x+26

mZD=2x-10

mZC≅mZD

-x+26=2x-10

Add x to both sides: 26=x-10

Add 10 to both sides: 36=x

Substitute x for 36 in the mZD equation: mZD=2(36)-10
