In this question, value of ¢ is sin 2¢ = 1. Now, it is asking about what will be the value of ¢ in 2.

Options:

(a) 15°

(b)45°

(c)30°

(d)60°

Correct Option will be (a) 15°

Solution:

→ 2sin 2¢ = 1

→ Putting 2 in R.H.S

→ sin 2¢ = 1 / 2

→ sin 2¢ = sin 30

→ sin and sin will be get cancelled

→ 2¢ = 30°

→ ¢ = 30° / 2

→ ¢ = 15°
