Question

if sin(A – B) =1/2 , cos(A + B) =1/2 ; where0° <A + B < 90°,and
A > B, then solveAandB
​

Answer 1

Answer:

sin(A- B ) = ½

=> sin(A-B) = sin 30

= > A - B = 30 .........(..1)

now,

cos(A+B ) = ½

=> cos(A + B) = COS 60

= > A + B = 60 .......(2)

NOW , ADDING BOTH THE EQUATION

A - B + A + B = 30 + 60

= > 2A = 90 ,

= > A = 45

PUTTING A = 45 IN (1)

WE GET B = 45°
