Question

If sin(a + b) = 1 and Sin (A - b) is equals to 1/2, 0 lesser than a + b is equals to 90 and A greater than B then find the value of a and b

Answer 1

ok so sin (a+b) = 1 I.e. 1=sin 90 degree so a+b = 90 degree. I.e. sin (a-b) =1/2 I.e. sin 30 degree = 1/2 so a-b = 30 degree so here a=60 degree and b= 30 degree
