Question

In right triangle ABC, Angle C is the right angle. Angle A measures 70°Find the measure of the exterior angle at angle C.

Answer 1

160

Explanation:

All triangle measures add up to 180 and a line is 180 as well

180-70-90=20

So the measure of C is 20

Now we just need to take the measure of C away from 180

180-20=160
