What is the measure of the angle if an angle if it is 300 less than five times its own supplement

Angle = _______ degrees

Answer 1

100°

Explanation:

Let the angle = x

Its supplement = 180 -x

5*(180 - x ) - x = 300

5*180 - 5*x - x= 300 {Distributive property}

900 - 5x - x = 300 {Combine like terms}

900 - 6x = 300 {Subtract 900 from both sides}

-6x = 300 - 900

-6x = -600 {Divide both sides by (-6)}

x = -600/-6

x = 100
