Bobbym, I suspect that your quote is a hint to use the height of the triangle to create two right triangles, and then use the Pythagorean Theorem.  That’s kind of what I’m looking for, an algebraic solution instead of a trigonometric solution, but I don’t know how to find the height of the triangle without using trigonometry.

If I have an isosceles triangle and know everything except the length of the base, is there a way to solve it other than using the law of sines or cosines?  In other words, I know all the angles and the lengths of the two equal sides, and want to know if there is a way to find the length of the other side using a method other than the law of sines or cosines.
