Question

sin(A+B) = 1 and cos(A-B) = 1/2, then values of A&B ​

Answer 1

Explanation:

Hope it helps u........

Answer 2

Answer:

sin(A+B) = 1

sin(A+B) = sin 90

A+B = 90 --------(1)

cos(A-B) = 1/2

cos(A-B) = cos 60

A-B = 60 --------(2)

Adding (1) and (2) we get

2A = 150

A = 75

Putting value of A in (1) implies

75+B = 90

B = 90-75

B = 15
