Homework Help: math

Posted by anthony on Saturday, April 11, 2009 at 11:16pm.

The cross section of an attic is in the shape of an isosceles trapezoid. If the height of the attic is 9 feet, BC=12 feet, and AD=28 feet, find the length of line AB to the nearest foot.

The triangle of the trapezoid is triangle ABE and the bases are BC and AD.



Could you also give me a link about the theorems and postulates of a two column proof?
