I need help with this question.
"The measure of the supplement of an angle is 60 less than three times the measure of the complement of the angle.find the measure of the angle".

• geometry -

180 ° - x = 3 * ( 90 ° - x ) - 60 °

180 ° - x = 270 ° - 3 x - 60 °

180 ° - x = 210 ° - 3 x

- x + 3 x = 210 ° - 180 °

2 x = 30 ° Divide both sides by 2

x = 15 °

Thanks!!!
