Answer:
x = 90
Step-by-step explanation:
∠1 = ∠4 ( corresponding angles are congruent ), thus
3x - 160 = x + 20 ( subtract x from both sides )
2x - 160 = 20 ( add 160 to both sides )
2x = 180 ( divide both sides by 2 )
x = 90
Answer:
x = 90.
Step-by-step explanation:
< 1 and < 4 are corresponding angles and are congruent if line a is parallel to line b. So:
3x - 160 = x + 20
2x = 180
x = 90.
