Answer 2

x = 8

Explanation:

Alternate Interior Angles Theorem

If a line intersects a set of parallel lines in the same plane at two distinct points, the alternate interior angles that are formed are congruent.

Therefore, equate the two angles and solve for x:

⇒ (8x - 4)° = 60°

⇒ 8x - 4 = 60

⇒ 8x - 4 + 4 = 60 + 4

⇒ 8x = 64

⇒ 8x ÷ 8 = 64 ÷ 8

⇒ x = 8
