Question 147676
Well, there's not much information to go by. 

Considering it's a triangle it is equal to 180 degrees.  If one angle (x) measures 45 then subtract from 180 to get 135.  If there is no other information given, I'm assuming you are referring to a triangle that has two sides/angles of equal measure. Therefore, the remaining two angles must be 67.5 degrees each.

If you have additional information on the word problem, let me know.
