Question

Two parallel lines are cut by a transversal, as shown below. What is the solution when solved for x?

(128°
12x

Answer 1

26

Explanation:

128° and 2x° are Co interior angles since the two parallel lines is cut by a transversal

so, 128+2x = 180(since sum of co interior angles always add to 180)

so, 2x = (180-128)

or, x = 52/2

or, x = 26
