Question

DOES ANYONE UNDERSTAND THIS???????????????/

Answer 1

(a) 4x=5(x-18)

(b) ∠A=∠B=360°

Explanation:

Corresponding angles : when two lines are crossed by a transversal , the angle in matching corners are called corresponding angles.

Since the corresponding are congruent.

Therefore,

∠A=∠B

⇔4x=5(x-18)

⇔4x=5x-90

⇔4x-5x=-90

⇔-x=-90

⇔x=90

Therefore ∠A=∠B= 4×90°=360°
