Question

If an angle is 60 degree less than two times its supplement then what is the measurement of the angle

Answer 1

Answer:

1st angle = x

2nd angle = 2(180-x) - 60

so total will be 180

1st angle + 2nd. angle = 180

x + 2 ( 180 - x ) - 60 = 180

x + 360 - 2x - 60 = 180

300 - x = 180

120 = x

1st angle = 120

2nd angle = 2(180 - 120) - 60

= 120 - 60

= 60
