Measure that angle III (Posted on 2004-09-07)

Triangle ABC has side AB=AC, and angle BAC = 20 degrees.

D is a point on side AC with AD=BC. Find angle DBC.

Solve this without trigonometry.

While doing some Statics homework, it occured to me that rather than use trig proper, we could break this into right triangles and use the pythagorian theorem to relate the sides. It is 1:30 in the morning and I have a class in 6 and a half hours, but I plan on pursuing this further when I get time tomorrow.
