The measure of one angle of an octagon is two times smaller that of the other seven angles. what is the measure of each angle?

Three numbers x, y, and z are in the ratio 2: 7: 8. if 12 is subtracted from y, then three numbers form a geometric sequence (in the order x, y–12, z). find x, y, and z. there are 2 sets.
