Two brothers build a pyramid-shaped fort. if the fort is 8 feet wide at its base, what expression could be used to calculate the height of the fort?

Step-by-step explanation:

We know that the base is 8 feet wide. The height of the pyramid is at the middle of this width, which forms a right triangle, with the angles formed by one side of the pyramid and the base.

Now, to find the expression of the height, we can use these given information and the trigonometric reasons. Specifically, we would use the tangent from the trigonometric reasons, because the height is the opposite leg to the angle, and the adjacent leg would be 4. So, the expression would be:

Therefore, the expression is
