Jane is building a model of a pyramid for a history project. It has a square base of side length 100 cm. The angle of elevation of the sides is 60 degrees. What is the height of Jane's pyramid.

Hi Ryan,

In the diagram of the pyramid below I want to look at the shaded triangle.

This is a right triangle with base 50 cm and and angle of 60o.

The height of this triangle is the height of the pyramid.
Can you find the height of the triangle?
