**Damon**, Monday, March 2, 2009 at 5:12pmStart with the 57.8 degree angle and the 35 feet opposite the angle

tan 57.8 = 35/d

where d is the horizontal distance from the building to the light

d = 35 / tan 58.8 = 21.2 m

so then you have a second triangle up top with 55 degree angle, (35-h) opposite, and 21.2 adjacent so

tan 55 = (35-h)/21.2

35 - h = 30.3

h = 4.7 meters (about 15 feet)
