Question

hey guys! if you know then please do tell I need help !!!​

Answer 1

sin(a+b)=√ 3/2  can happen only when a+B = 60 degree as sin60=√ 3/2

a+B=60 (1)

similarly cos (a-b)=√ 3/2 only when a-b=30 as cos 30=√ 3/2

a-b=30 (2)

adding (1) and (2)

a+B+a-b=30+60

2a=90

a=45

hence b will be 15

a=45

b=15

Answer 2

THIS IS UR ANSWER
