Ответ:
1. 40. Add up all the known angles, and subtract then from 360, since all the angles to get her make a circle. This will give you the unknown value. 160+75+45=280. 360-280=40
2. 140 Repeat. 125+73+22=220. 360-220=140
3. 107 Repeat. 226+27=253. 360-253=107
4. 163 Repeat. 120+36+41=197. 360-197=163
Hope this helps!
