Answer:

x=27

Step-by-step explanation:

3x+9 is a right angle because 3x+9 + a right angle make a straight line

3x+9 +90 = 180

Subtract 90 from each side

3x+9 = 90

We now can solve for x

3x+9-9 = 90-9

3x = 81

Divide each side by 3

3x/3 = 81/3

x=27

Artemon [7]

Ratio of the free throws completed to attempted free throws is given to be 4:7. This ratio should be equal to the ratio of the next case. Let x be the number of free throws attempted. The proportion takes a form of,
(4 completed / 7 attempted) = (12 completed / x attempted)
Solving for x gives x = 21. Thus, the answer is letter c. which is the second among the choices.
