so you know that in the triangle in the left of the picture, there is an angle measuring 45 degrees, and another angle measuring 80 degrees. Add them up to get 125. Subtract 180-125 to get the missing angle for that triangle. Reason: A+B+C=180, where the variables represent the angle degrees

oregonduck (oregonduck):

55 degrees is the missing angles HINT HINT
