I hope I help, the answer should be -120 if I'm. Correct
Answer:
Step-by-step explanation:
Two angles each =x because both are equal.
All triangles have angles adding to 180 degrees
The angle that isn't = x is 82 degrees.
x + x + 82 = 180 Subtract 82 from both sides
2x + 82 - 82 = 180 - 82 Combine
2x = 98 Divide by 2
2x/2 = 98/2
x = 49
angle 1 = 49
angle 2 = 49
angle 3 = 82
