A. 0°
B. 30°
C. 45°
D. 60°

Answer 1

Answer:

Step-by-step explanation:

60°

Answer 2

A. 0°

Step-by-step explanation:

Given: Sin 2A = 2 sin A is true

Let's assume A = 0°, then 2A will be 0° as well.

So Sin A will be Sin 0° and Sin 2A will be Sin 0°.

Sin 2A = 2 Sin A will be true when A is zero.

Option A is the answer.
