Answer:
60* Hope this helped!
Explanation:
There are two ways to do this:
1: I know that this is an equilateral triangle because 180/3= 60, since i know that two angles are already 60* i immediately know that angle c is 60* also.
2: We already have two angles, we just need to figure out the third.
Since a triangle is 180* we just subtract angle a and b to get c
180-60+60=x
180-120=x
x=60
