Rudy is trying to estimate the height of the water tower next to his school. To do so, he looks out of a second-story window, 225 meters from the water tower. Rudy's line of sight to the top of the water tower makes a 21° angle of elevation, and his line of sight to the base of the water tower makes a 4° angle of depression.
What is the height of the water tower?
