Consider the cross-sectional right triangle shown in the figure.

One of its sides is the height of the pyramid, with length H. The other side is half of the square base, so its length is 81 m. The hypotenuse of this triangle is the height of one of the faces.

By right triangle trigonometry,

$\displaystyle{ \tan52^o= \frac{H}{41 \ m }$ ,

thus,

$H=\tan52^o\cdot41 \ m=1.28 \cdot41 \ m=52 \ m$ .

Answer: C) 52 m
