From a point 120 feet from the base of a plant building the angle of elevation to the roof line of the building is 38 degrees. The angle of elevation to the top of an antenna is 43 degrees. The antenna is attached to the nearest edge of the roof and the ground is flat. The height of the antenna is ________ feet. Round to two decimal places. I figured out that the height of the building, using the angle of 38 degrees, is 152.28 feet. I don't know how to figure the problem to solve for the height of the angennae.
