Question

LAST OF MY GEOMETRY PLZ HELP

Answer 1

Answer:

Step-by-step explanation:

14) 2x - 10 = 80       {alternate interior angles are equal}

     2x = 80 + 10

      2x = 90

        x = 90/2

       x = 45°

15) 3x + 120 = 180    { co interior angles are supplementary}

     3x = 180 - 120

      3x = 60

        x = 60/3

        x = 20°

16) 3x + 15 = 135     {corresponding angles are equal}

      3x = 165 - 15

       3x = 150

          x = 150/3

          x = 50°
