Answer:
<h3>∴∠B=30°</h3>
Step-by-step explanation:
Complementary:
Two angles is said to complementary when the sum of two angles is 90 degree.
Given that,
∠A and ∠B are complementary.
Then, ∠A + ∠B = 90°
Cos A = 0.5
Since
∠A + ∠B = 90°
⇒ 60°+ ∠B = 90° [ plug ∠A= 60°]
⇒∠B=90°-60°
⇒∠B=30°
<h3>∴∠B=30°</h3>
