PLS WILL GIVE 100 POINTS AND MARK BRAINLEST

Answer:
angle 2 = 128 because of a rule that I unfortunately cannot remember the name of....
angle 6 = 180 - 47 = 133
because a straight line = 180 degrees
angle 3 = 180 - 128 = 52
Same reason as angle 6
angle 1 = 52 + 47 = 99
180 - 99 = 81
Sum of the angles in a triangle = 180
All of the underlined numbers are the answers
