Stephanie is at the top of an overlook below a waterfall in Yosemite. She knows that the overlook is exactly 200 feet away from the waterfall. Stephanie measures the angle of elevation to the top of the falls from her position and sees it is 22°. When she measures the angle of depression to the base of the falls, she learns that it is 61°. Using this information, what is the height of the falls?
What is approximately 441.6ft?
