Question

In the figure d, e, and f are parallel lines. What is the value of x?

Answer 1

X=150

Explanation:
You take 180 as a straight line is 180° and you make the equation 180-60=x-30 Then you subtract 180 and 60 which equals 120 then add 30 to both sides and the equation after that should look like 150=X and thats your answer.

180-60=x-30
120=x-30
+30. +30
150=X

Answer 2

x = 150

Explanation:

Corresponding angles

180 - 60 = x-30

120 = x-30

150 = x
