Question

if sin(A+B)=√3/2 and sin(A-B)=1/2.find a and b.A>B​

Answer 1

Answer:

a=45°, b=15°

Step-by-step explanation:

sin(A+B)= sin 60°                                        sin(A-B) = sin 30°

⇒ A+B = 60°                                               ⇒ A-B = 30°

From the above equations, we get

A = 45° and B = 15°
