If all the vertices of a triangle are on the circle and one side of the triangle is the diameter of the circle it is a right angle. Find the length of the diameter (AC) if Ab =8 and BC = 15.

The diameter is the longest side, and the longest side of a rt. triangle is
the hyp.
(AC)^2 = 8^2 + (15)^2 = 289,
AC = 17.
