Answer :

Answer:

x = 9

Step-by-step explanation:

Given information the pair of parallel lines are cut by a transversal.

A and B are alternate exterior angle so their measures are equal to each other.

We can write the following equation based on these informations:

m∠A = (4x − 2)° = m∠B = (6x − 20)° transfer like terms to the same side of the equation

20 - 2 = 6x - 4x subtract

18 = 2x divide both sides by 2

9 = x
