1)120°
2)110°
3)140°
4)100°

Answer 1

Answer:

3) 140°

Step-by-step explanation:

70° +  80° + 70° + x  =  360°  ( since exterior angle property )

                 220° + x  =  360°

                             x  =  360° - 220°

                             x  =   140°

Answer 2

Answer:

The answer is 140°

sum of exterior angles is equal to 360
