Answer:

C. 15

Step-by-step explanation:

The following proportional can be set-up for the figure given:

[tex] \frac{x + 3}{x} = \frac{10 + 2}{10} [/tex]

Solve for x

[tex] \frac{x + 3}{x} = \frac{12}{10} [/tex]

[tex] \frac{x + 3}{x} = \frac{6}{5} [/tex]

Cross multiply

[tex] 5(x + 3) = x(6) [/tex]

[tex] 5x + 15 = 6x [/tex]

15 = 6x - 5x

15 = x

x = 15
