Question

If sin (A+B)=1 and cos (A-B)=underroot 3 over 2. find A and B

Answer 1

sin(A+B)=1
(A+B)=90...(1)
cos(A-B)=√3/2
(A-B)=30...(2)
Add 1 and 2
2A=120
A=60
B=30

Answer 2

Hey... I think this can be ur answer!!

Sin(A+B) = 1
Sin (A+B) =sin90
A+B=90

Cos (A-B) =root3/2
Cos (A-B) =30
A-B=30

Now,
Adding both
2A=120
A=60
B=30

HOPE IT HELPS YOU ☺️☺️☺️
