Answer:
Angle "c" would be 9 degrees (a very small angle!)
Step-by-step explanation:
In a triangle, all of the angles must equal 180 degrees.
57, the measure of angle "a", plus 114, the measure of angle "b", would equal 171 degrees.
So, 180 - 171 = 9, which would be the value of the remaining angle "c"
