C-10-Q094mediumsingle_mcq

Hence the angle of elevation of the sun is—

a $15^\circ$
b $30^\circ$
c $45^\circ$
d $60^\circ$

ব্যাখ্যা

Since $\tan(\text{elevation}) = \frac{1}{\sqrt{3}}$ and $\tan 30^\circ = \frac{1}{\sqrt{3}}$ , the angle of elevation is $30^\circ$ . This is a standard reference angle.
