I think….. Measure for lst angle Find total ratio =11 2/11*110° Reason why we multiply by 110° because a triangle adds up to 180° but we remove 70° from 180° we get 110° to find the measures for the two angles Okay sooo…. 2/11*110°=20° Measure for second angle 9/11*110°=90°
So to prove our answer we add all the three angles and see if they will add up to 180° 90°+20°+70°=180° I don’t know if it’s right but this is what I think Hope it helps
