30 degrees Not likely.
60º
If two angles of a triangle each measure 55 what is the measure of the third angle?
It will be an equilateral triangle and each interior angles measure 60 degrees.
The sum of a regular polygon's exterior angles is 360. 360 divided by 3 is 120.
It is the regular equilateral triangle whose each exterior angle is 120 degrees
60 degrees
