Answer:
60°
Step-by-step explanation:
Because of the rule that all triangle's angles must measure to 180°.
So I did...
60+60=120
180-120= 60
Answer
60 degrees
A triangle is 180 degrees. So if you add both 60 degrees it would equal 120, substracted by 180 and you'll get 180. Or if you want to go the faster way, remember that a triangle will equal 180.
