1. A triangle always adds up to 180° so you would add both the angles you know 55° plus 55° which equals 110° then subtract it from 180° and you should get 70°
2. Add 40° and 35° which equals 75° then subract it from 180° which is 105°
Well, at least you improved. But maybe you should use another source besides brainly for your tests. Sometimes people put the wrong answers just to get points.
