20) triangles equal 180 degrees so if the given is 65 and 50 =115 180-115=65 X=65 degrees 21) your given 34 and 56 = 100 180-100 X=80 degrees 22) the pink square is a right angle. Right angles are 90 degrees. So 90+53=143 180-143 X=37 degrees 23) the two angles you’re given are 25 and 102 = 127 180-127 Measure of angle Q is 53 degrees
