Step-by-step explanation:
step 1. 10x - 10 = 8x + 14. alternate exterior angles
step 2. 2x = 24. subtract 8x from each side and add 10 to each side
step 3. x = 12
step 4. 10x - 10 = 15y + 35. vertical angles
step 5. 10(12) - 10 = 15y + 35
step 6. 110 = 15y + 35
step 7. 75 = 15y
step 8. y = 5
step 9. the angles are 10x - 10 or 10(12) - 10 = 110°
step 10. except for 12y + 10 which is 12(5) + 10 = 70°.
