Question

If sin a = ½ and cos b = ½, then a + b = ________​

Answer 1

Question :-

• If sin a = ½ and cos b = ½, then a + b = __

Solution :-

Sin a = ½ and Cos b = ½

We know that -

sin 30 degree = ½

And Cos 60 degree = ½

Hence,

Sin a = sin 30

a = 30

And

Cos b = Cos 60

b = 60

So, a + b = 30 + 60 = 90 degree Answer

Answer 2

Sin a=1/2
sin a=sin 45
So,a=45
Now,
cos b=1/2
cos b=cos 45
b=45
a+b=45+45
=90
