7: 125° (vertical angles)
8: 53° (corresponding angles)
9: 113° (vertical angles)
10: x = 7 (corresponding angles, so you can set them equal to each other and solve, which results in 75 = 11x - 2, add two to both sides, and then divide by 11)
Have a nice day!
I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)
