Well a triangle has the total of 180 degrees right? so try subtracting 180 by the total of the two angles.

60(2)-180=?

xapproachesinfinity · Answer

this is an equilateral triangle
all angles are 60 degrees

mathstudent55 · Answer

180 - 2(60) = 180 - 120 = 60
The third angle also measures 60 degrees.
You have a triangle with all congruent angles measuring 60 degrees.
Now you need to pick the correct answer.
