Answer:
60, 45, 75.
Explanation:
A triangle must be; when you add up all its angles the number is 180.

Ex: Angle 1+Angle 2+Angle 3 = 180
-
First, let's try 60,40,70.
60+40+70 = 170, which isn't 180.
Next...
60+45+75 = 180, so that is the answer.
If you still want to try the third one...
60+45+80 = 185
