A $16$ m ladder leans against a wall making $60^\circ$ with the ground. The height it reaches on the wall equals—

a $16 \cdot \sin 60^\circ$
b $16 \cdot \cos 60^\circ$
c $16 \cdot \tan 60^\circ$
d $8$

ব্যাখ্যা

The wall height is the side opposite the $60^\circ$ angle, and with the $16$ m ladder as the hypotenuse, this side equals hypotenuse times sine, i.e. $16\cdot\sin 60^\circ$ .
