Question 40734: A recent land survey was conducted on a vacant lot where a commercial building is to be erected. The plans for the future building construction call for a building having a roof supported by two sets of beams. The beams in the front are 8 feet high and the back beams are 6.5 feet high. The distance between the front and back beams is 8 feet. At what angle will the roof lay on the front beam?

The front beam height = 8.00
The Rear Beam height = 6.50
Diff in height = 1.50
Tangent of the angle the front beam makes = 8/1.5 =5.3333
The angle is between 79 and 80 degree ( 5.14 & 5.67) = 79.3 deg (approx)
