Question

Evaluate sin60° +cos30°​

Answer 1

Answer:

sin 60°=√3/2

cos 30°=√3/2

sin60°+cos30°=2√3/2=√3

Answer 2

Step-by-step explanation:

$\sin60 \degree + \cos30 \degree \\ \frac{ \sqrt{3} }{2} + \frac{ \sqrt{3} }{2} \\ = \frac{ \sqrt{3} + \sqrt{3} }{2} \\ = \frac{\cancel{2} \sqrt{ 3} }{\cancel{2}} \\ = \sqrt{3}$

$\bold{As \: we \: know,} \\ \fbox\bold{\sin60 \degree= \frac{ \sqrt{3} }{2} \: and \: \cos30 \degree = \frac{ \sqrt{3} }{2} }$
