Answer:
angle A: 59 degrees
angle B: 48 degrees
angle C: 73 degrees
Step-by-step explanation:
in every triangle, if you add up all of the degrees, you get 180
x + 73 + (x - 11) = 180
2x + 62 = 180
2x = 118
x = 59
then, you can just insert x into the respected expressions to solve for their angles
A. x = 59 degrees
B. x - 11
59 - 11
48 degrees
C. 73 degrees
