  6. Mrs. Rivas Same-side Interior angles 103 (x − 26) + x = 180 x − 26 + x = 180 77 2x − 26 = 180 2x = 206 x = 103 103 + 77 = 180

  7. Mrs. Rivas Corresponding angles (3x − 5) = (x + 55) 3x − 5 = x + 55 2x − 5 = 55 2x = 60 x = 30 3(30) − 5 = 30 + 55 90 − 5 = 30 + 55 85 = 85

  8. Mrs. Rivas Linear Pair angles = Suppl. (x + 20) + (x + 10) = 180 95 85 x + 20 + x + 10 = 180 2x + 30 = 180 2x = 150 x = 75 95 + 85 = 180

  9. Mrs. Rivas Linear Pair angles = Suppl. (y − 40) + y = 180 110 y − 40 + y = 180 2y − 40 = 180 70 2x = 220 x = 110 110 + 70 = 180

  10. Mrs. Rivas Alternate Exterior angles (2x + 6) = 42 42 2x + 6 = 42 2x = 36 x = 18

  11. Mrs. Rivas Same-side Interior angles (3x − 17) + 98 = 180 82 3x − 17 + 98 = 180 3x + 81 = 180 3x = 99 x = 33 98 + 82 = 180

  12. Mrs. Rivas Same-side Interior angles (2x + 20) + (6x + 24) = 180 54 2x + 20 + 6x + 24 = 180 8x + 44 = 180 126 8x = 136 126 + 54 = 180 x = 17

  13. Mrs. Rivas Alternate Exterior angles 132 (2x + 2) = (3x − 63) 2x + 2 = 3x − 63 2x = 3x − 65 − x = − 65 132 x = 65

  14. Mrs. Rivas Linear Pair angles = Suppl. (5x − 5) + 140 = 180 5x − 5 + 140 = 180 40 5x + 135 = 180 5x = 45 140 + 40 = 180 x = 9

  15. Mrs. Rivas Same-side Interior angles 68 (4x − 8) + 112 = 180 4x − 8 + 112 = 180 4x + 104 = 180 4x = 76 x = 19 112 + 68 = 180
