Answer 2

Answer:

Step-by-step explanation:

1) y = 80° (opp angles)

   x = 180 - 80

      = 100°

2) let x be the unknow angle

 x + x = 90°

     2x = 90°

       x = 90/2

       x = 45°

3)

x + 60 = 180

         x = 180 - 60

         x = 120°

4)

x - 1 + x + x + 1 = 180 (given

                  3x = 180

                     x = 180/3

                     x = 60°

x - 1 = 59 , x = 60 , x + 1 = 61

5) from statement

2x = y - 30

 x = y/2 - 15

x + y = 180

y/2 - 15 + y = 180

          3y/2 = 180 + 30

             3y = 210/2

               y = 105/3

               y = 35°

             x = 35 - 30

             x = 5°
