Question

EXERCI
Evaluate the following:
sin 60 cos 30 + sin 30
cos 60​

Answer 1

Step-by-step explanation:

sin 60cis30+sin30cos60

= 0.78

Answer 2

$\huge{\mathcal{\boxed{\blue{Solution}}}}$

$sin60 \cos30 + sin30cos60 \\ = \sin(6 0 + 30) \\ = \sin(90) \\ = 1$

Identity used:

SinACosB+CosASinB=Sin(A+B)
