Trig really need this?
A roof rises at an angle of 20degree flar eWall front of the storage shed to the rear wall. the front wall is 11.5 meters high and the back wall is 15.5ft tall find the length of the roof line and the depth of the house from front to back
See the diagram, the password is Trig Together http://www.4shared.com/dir/895177/785be83a/sharing.html = Depth Without Hypotenuse = Roofline = Opposite / Hypotenuse Cos = Adjacent / Hypotenuse Sin 20 degrees = 0.3420 0.9396 Cos 20 º = sin 20 degrees = 0.3420 = 4 / roofline, so Attics Emphasize = 4 / 0.3420 = 11.6959 = 0.9396 Cos 20 º = Adjacent / 11.6959, so depth = 0.9396 = 10.9894 11.6959 * Make sure you understand the work do not copy the answer: o)
