Question

I need help doing this idk how to do it, can you please explain it to? Instead of just giving me the answer

Answer 1

45° would be the correct answer

Answer 2

Answer:

A=55

B=80

C= x

So always the sum of the angles of a triangle should be 180 so

55+80+x=180

135+x=180

X= 180-135=45

Therefore, angle C = 45
