8. Introduction to Trigonometry

easy

$\frac{\sin 60+\cos 30}{1+\sin 30+\cos 60}=\ldots \ldots \ldots$

A

$\frac{1}{\sqrt{2}}$

B

$\frac{1}{2}$

C

$1$

D

$\frac{\sqrt{3}}{2}$

Solution

$\frac{\sin 60+\cos 30}{1+\sin 30+\cos 60}=\frac{\frac{\sqrt{3}}{2}+\frac{\sqrt{3}}{2}}{1+\frac{1}{2}+\frac{1}{2}}=\frac{\sqrt{3}}{2}$
