Answer:
x = 120°
Explanation:
From the triangle, we know that each corner is 60° because they have the half circle markers which mean they are equal. a triangle only has 180° so divide 180 by 3 to get 60. From there, we see that x is a straight line, which only has 180 degrees.
subtract the 60 from the triangle piece away from 180 and you get 120 degrees.
