Question

hey everyone!!! help please......

Answer 1

We know Tan 60° = √3 and Tan30° = 1/√3

So , A-B must be 30
and A+B must be 60°

U can easily find A & B

Answer 2

Sin A = Sin 90°
Using trigonometric table

A = 90°

Tan ( A - B) = √3

Tan (A - B) = Tan 60°.

A - B = 60°

90°- B = 60°

90° - 60° = B

Answer. A = 90°
B = 30°
