Step-by-step explanation:

Angles are the following

1. 110°

Angle 3 = Angle 1

2. 70°

total angles 1,2,3 4 is 360

360 – (110×2) = 140 ÷ 2 = 70

3. given 110°

4. 70°

Angle 2 = Angle 4

5. 110°

total angle of 5 and 8 is 180

180 – 70 = 110

angle 1 = angle 5

6. 70°

Angle 6 = Angle 8

7. 110°

total angle of 7 and 8 is 180

180 – 70 = 110

angle 3 = angle 7

8. 70°

given = 70°
