Question

Line l and m are parallel lines cut by transversals p and q as shown in the diagram.

What is the value of X?

A.135
B.45
C.23
D.68

Answer 1

D

Explanation:

∠1 = 2x - 1 {Vertically opposite angles}

2x - 1 + 45 = 180 {Co interior angles}

2x + 44 = 180

2x = 180 - 44

2x = 136

x = 136/2

x = 68
