What are the answers for 8,9,10?

1 Answer

  • 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.
