A5.5 ft boy casts a shadow that is 8.25 ft long. a nearby tree casts a shadow that is 18 ft long. how tall is the tree?

Wow I hate it when we have these types of questions, like when is my boss or when am I ever gon use this in life. The equation uses Pythagorean’s theorem and when you get the end of the boys shadow touching the floor it is the vertical angle for the trees shadow, then you just reverse engineer the problem... someone else will do it
