Step-by-step explanation:

1. Vertical Angles

2. complementary angles= 90

3. vertical Angles

4. Supplementary Angles- 4x+28=180

5. vertical Angles :2x+5=55

6. Right Angle: 7x+8x=90

7. Supplementary Angles: 119+3x+7=180

8. vertical Angles: 3x=156

9. vertical angles: 8x-4=116

10. right angles: 3x+7+4x-1=90
