The exterior angle theorem states that an exterior angle is equal to the sum of its remote interior angles.

So...

80+20=m<CAD

m<CAD=100°

Answer:

100 degrees

Step-by-step explanation:

In a triangle, there's 180 degrees total. So we need <CAB to get 180 degrees which can be found by setting up the following equation and solving:

80+20+x=180

100+x=180

x=80

Since <CAD and <CAB are supplementary angles, they both must add up to 180 degrees, so we set up the following equation and solve:

80+x=180

x=100

So <CAD is 100 degrees

Hope this helped!
