Question

What is the exterior angle of triangle ABC

These are the points:
A=3, B=10, C=6

Answer 1

Based off of what I can see in the photo (its too blurry to know for sure) and what I think you're asking:

The angle of a triangle always adds up to 360degrees, so base it on that and the acute and obtuse angles and get the degrees from there, the angle would be those degrees you find or <10, 5, 4 (what I assume is a 5)
