Answer 1

x = 2

Explanation:

Corresponding angles are equal

Therefore, 7x + 3 = 8x + 1

Subtract 7x from both sides:

⇒ 3 = x + 1

Subtract 1 from both sides:

⇒ 2 = x

Answer 2

x = 2°

steps:

• 7x + 3° = 8x + 1°

• 7x - 8x = 1° - 3°

• -x = -2°

• x = 2°

reason:

corresponding angles have same angle measure.
