Z1 = 3x - 160 and 24 = x + 20
x = [?]

Answer 1

x = 90°

Explanation:

A // B

When two parallel lines are crossed by a transversal, the angles in matching corners are called corresponding angles and they are equal.

∠1 = ∠ 4

3x - 160 = x + 20

Add 160 to both sides

3x - 160 + 160 = x + 20 + 160

3x = x + 180

Subtract x from both sides

3x - x = x -x +180

2x = 180

Divide both sides by 2

2x/2 = 180/2

x = 90
