Question

ZE and ZF are vertical angles with mZE=81 +8 and mZF=2.0 + 38.

What is the value of x?
Enter your answer in the box.
X=

Answer 1

x=5

Since they are vertical angles, it means that they are congruent. So you have to set it equal to each other.

8x+8=2x+38

Subtract 2x from both sides

6x+8=38

Subtract 8 from both sides

6x=30

Divide 6 on both sides

x=5
