Two angles are supplementary. The first angle has 20 degreesmore the second angle. How ma y degrees are in each angle?

100 and 80

Step-by-step explanation:

Let x = be the first angle

x-20 is the second angle

They are supplementary so they add to 180

x+x-20 = 180

Combine like terms

2x-20 = 180

2x-20+20 = 180+20

2x = 200

Divide by 2

2x/2 = 200/2

x = 100

The first angle is 100 and the second is x-20

x-20 = 100-20=80

The two angles are 100 and 80
