Use the following diagram for questions 4 - 6.

what is the relationship between the two angles?
a-complementary
b-linear pair
c-vertical angles

what rule applies to the two angles?
a-they add up to 90
b-they are congruent (equal)
c-they add up to 180

solve for x.
a-x = 23
b-x = 49
c-x = 36
d-x = 18

1. C

2. B

3. B

Step-by-step explanation:

Vertical angles are the angles opposite each other when two lines cross, thus angles with measures (x+77)° and 126° are vertical angles.

Vertical angles are congruent.

Hence,

.24

step-by-step explanation:

the probability is   .24

the first player had the highest probability of getting a silver marble

the game could be made fair by adding back the marble that was drawn after each draw

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.
