The sum of the measures of the angles of a triangle is 180. The sum of the measures of the second and third angles is three times the measure of a first angle. The third angle is 15 more than the second. Let x, y, and z represent the measures of the measures of the first, second and third angles, respectively. Find the measures of the three angles.
