8. angle 2 is 50 (we find this subtracting angle 5 from 180) , so we can use this and angle 4 to find 3. 180  50  70 = 60 degrees. Angle 3 is 60 degrees
9. angle 2 is 38 (same method as before) so we find angle 3 from 180  38  65 = 77 degrees. 3 + 1 = 180, so angle 1 is 180  77 = 103. Angle 1 is 103 degrees
10. Simply use the triangle. 180  125  23 = 32. Angle 2 is 32 degrees.
