Question

Find the value of x​

Answer 1

x = 42˚

Explanation:

1) Find the angle shared by 138˚. 180-138 = 42˚.

2) Now we know that one of the angles in the pentagon is 42˚.

3) the other opposite angle is 138˚ as well.

Hopefully this makes sense! I attached a picture below.

Answer 2

6x = 360-138

x= 222/6

x= 37°
