A house has a rectangular base and a roof that peaks along a line above the center of the house and parallel to the length of the house. This roof slopes downward from the peak to each edge at an angle of 37.0° with the horizontal. The length of the front of the house is 10.0 meters. The width of the house is 8.00 meters. The height from the front of the house up to the edge of the roof is 5.00 meters.
