Question

sin (A + B ) =1 and sin(A - B) = 1/2 , then the value of A and B respectively are 1 point 45 and 15 30 and 15 60 and 30

Answer 1

Answer:

A = 0.75 and B = 0.25

Step-by-step explanation:

(A+B) = 1

(A-B) = 1/2

(A+B) + (A-B) = 1 + 1/2

or, A+B+A-B = 1 and 1/2

or, 2A = 3/2

or, A = 3/4

If, A is 3/4 then B is

(A+B)-A = 1 - 3/4

or, B = 1/4

So, A = 3/4 = 0.75

A = 3/4 = 0.75 B = 1/4 = 0.25
