Answer 2

Step-by-step explanation:

We know that,

tan 45° = 1 .......... (1)

But in the question,

tan (3x-15°) = 1. ...........(2)

On comparing 1 and 2, we have,

tan (3x-15°) = tan 45°

3x-15° = 45°

3x = 45°+15°

3x = 60°

x = 60°/3

x = 20°

Therefore,the value of x is 20°. Hence, option 2 is correct.

Hope it helps you.

Good Luck.
