Answer:

9. x=102

10. x=56

11. x=104

12. x=138

Step-by-step explanation:

9. In this problem, they are alternate exterior angles, meaning they are the same value. x=102

10. x is a corresponding angle, meaning they are the same. x=56

11. There are consecutive interior angles. The sum of these two angles is 180. to find x, subtract 76 from 180. 180-76 = 104 x = 104

12. These two angles are verticle angles, meaning they are equivalent. x = 138

Orange then green or green the orange

The probabilities are:

P(o&g) = 2/10*2/9 = 2/45
P(g&o) =2/10*2/9 = 2/45

Required probability is:

P = 2/45*2 = 4/45 = 0.08889

Correct choice is C
