The measure of one angle is thirteen more than six times the measure of another angle. The sum of the measures of the two angles is 90°. Determine the measures of each angle in degrees.
x = measure of one angle {one angle is thirteen more than six times the other}6x + 13 = measure of other angle x + 6x + 13 = 90 {the sum of the measures of the two angles is 90} 7x + 13 = 90 {combined like terms} 7x = 77 {subtracted 13 from each side} x = 11 {divided each side by 7} 6x + 13 = 79 {substituted 11, in for x, into 6x + 13} 11° and 79° are the two anglesAsk the House
