i'm doing a pyramid project and i'm having some trouble with the dimensions. if my base is 14in. then what should my angle and height be?


Hi Becka,

The angle and height can be pretty much anything you want.

In the diagram above, the height is h = |AB| and since the base is 14 inches, |BC| = 7 inches. Thus

tan(BCA) = h/7  or h = 7 tan(BCA)

Hence if you chose the value of either h or the measure of the angle BAC you can calculate the other.
