I’m leaning towards option C, 20 feet, but I need to double-check my work on the triangle dimensions.

I remember a similar question where we had to find the height of a triangle, but I’m not sure if it was exactly like this one.

I think we might need to use the Pythagorean theorem here since it's a right triangle.
