Question

If an angle and its half form a pair of supplementary angles , what are the measures of the angles

Answer 1

100 degrees

Step-by-step explanation:

2x + x + 30 = 180

3x + 30 = 180

3x = 180 - 30

3x = 150

x =

150

3

x = 50

both angles

2x = 2

×

50 = 100

x + 30 = 50 +30 = 80

larger angle is of 100 degrees
