• ANGLE B = ANGLE A = 40° ( CORRESPONDING ANGELS ARE EQUAL)

• ALTERNATE INTERIOR ANGLES

Answer 2

Step-by-step explanation:

1. ∠b = ∠a (corresponding angle)

Hence, ∠b = 40°.

2. ∠b and ∠c are alternate interior angle (the pair is called alternate interior angle).

∠b = ∠a (alternate interior angle).

That's all.
