I am guessing at # 9 because there is no picture...but interior angles of a triangle add up to 180
so if 1 angle is 44.1 and the other angle is 47.6, then the third angle is : 180 - (44.1 + 47.6) = 180 - 91.7 = 88.3.....and this is an acute triangle ================== 2 pairs of corresponding angles : <2 and < 6.......< 1 and < 5 2 pairs of alternate interior angles : < 3 and < 6....< 4 and < 5 m < 7 = 106 m < 8 = 74 ================= < KMA + < YMA = 180
