Question

evaluate Cos 60 degree sin 30 degree + sin 60 degree cos 30 degree

Answer 1

Heya !!

Here is your answer.

Cos 60 = 1/2

Sin 30 = 1/2

Sin 60 = root 3/2

Cos 30 = root 3/2

Putting these values,

==> 1/2 * 1/2 + root 3/2 * root 3/2

==> 1/4 + 3/4

==> 4/4

==> 1

Your answer is 1.

Hope it helps.
