Hey... I think this can be ur answer!!
Sin alpha =1/2
Sin alpha =sin 30
Alpha = 30 degrees
Cos beta =1/2
Cos beta =cos 60
Beta =60 degrees
Now
Alpha +beta = 30 + 60 = 90
Sin alpha =1/2
Sin alpha =sin 30
Alpha = 30 degrees
Cos beta =1/2
Cos beta =cos 60
Beta =60 degrees
Now
Alpha +beta = 30 + 60 = 90
