...Help?
I’m co fused on how to work with exterior angles, so I don’t know this one...

What is the value of x?
100
70
O A. 10°
O B. 300
O c. 70°
O D. 170

Answer 1

Answer:

B. 30

Step-by-step explanation:

A line is 180 degrees, so when we have 100, we subtract that from 180 to get the interior angle of 80.

A triangle has a sum of 180, so we just subtract 80 and 70 from 180 to get 30.

Hope this helps
