Answer:
C. 120º
Step-by-step explanation:
so we know that the inside of a triangle is 180º and since all the measures are the same we can do 180/3 to find how much each angle is.
180/3 = 60º
now we also know that a straight line is equal to 180º and since we already have one angle, all we have to do is subtract 60 from 180.
180 - 60 = 120º
