Question

a) If tan (A+B)=1 and cos (A-B)= root 3/4 0<A+B <90
A >B then find values of A & B​

Answer 1

→ GIVEN:

tan(A+B) = 1

→ (A+B) = 45°

cos(A-B) = √3/2

→  (A-B) = 30°

Now,

A + B = 45° ⊕⊕

A - B = 30°

Adding them, we get

2A= 75°

→ A= 75°/2

Putting the value of A in ⊕⊕ we get

→ B = 15°/2
