A+B=90
A-B=30
by solving this you will get
A=60.
B=30.
A-B=30
by solving this you will get
A=60.
B=30.

heya ,
it's so easy
sin(A+B)=1
=)sin(A+B)=sin90°
A+B=90°______1)
and again..
sin(A-B)=sin30°
A-B=30°_____2)
adding 1 ) and 2) we get ..
2A=120°
A=60° and again putting in 1 st equation.
we ,get ,
B=30°
hope it help you
