Answer:
67.5
OR
45, 90
Explanation:
The answer would either be 135, or 45, 90.
This is because typically whenever we see a all sides of a triangle equal 180, we can already understand there is a trig relationship, and when they give us one angle being 45, we see this as a 45-45-90 Triangle. (x, x, x*sqrt(2))
Or the simple but probably wrong answer would be 45 - 180 = 135. 135/2 = 67.5
