Question

If sin (A+B) = 1 and sin [A-B) = 1/2, 0.
- A+B 90° and A B then find A and B.​

Answer 1

Answer:

14-Mar-2018 — The answer is 1. Step-by-step explanation: Given and . we have to find the value of tan(a+2b).tan(2a+b). As,. ⇒ a+b=90° → (1). and. ⇒ a-b=30° ...

Step-by-step explanation:

Answer 2

sin(A + B) = 1 = sin 90°

A + B = 90° ---------(i)

sin (A-B) = 1/2 = sin 30°

A - B = 30o ---------(ii)

Solving eq. (i) and (ii), A = 60° and B = 30°
