I do not understand your post.

Exterior angle? Where? Which one?

"find the other interior opposite angle"

Other? Interior? Opposite what?

"and the third angle of each triangle"

How many angles do you expect someone to find?

Please re-read your post. Think of it like this--If you knew absolutely nothing about this problem, could you solve this problem the way your post is worded?
