Question

Evaluate

Sin 60° Cos 30° + Sin 30° Cos 60°

Answer 1

Hey

Here is your answer,

= Sin 60° Cos 30° + Sin 30° Cos 60°
=Sin (90° - 30° ) cos 30° + Sin 30° Cos (90° - 30°)
=Cos 30° Cos 30° + sin 30° sin 30°
=cos^2 30° + sin ^2 30°

By using the formula sin^2 theta + cos^2 theta =1

=1

Hope it helps you!

Answer 2

Hey friend!

Here's your answer.
_____________________________


$(\frac{ \sqrt{3} }{2} )( \frac{ \sqrt{3} }{2} ) + ( \frac{1}{2} )( \frac{1}{2} ) \\ \\ \frac{3}{4} + \frac{1}{4} = \frac{4}{4} \\ \\ = 1 \: answer$

Hope this helps.
