Question
Solve #7
Suppose you need to find the height of a tall building. Standing 20 meters from the base of the building, you aim
a laser pointer at the closest part of the top of the building. You measure that the laser pointer is 4° tilted from
pointing straight up. The laser pointer is held 2 meters above the ground. How tall is the building?
