V125BC [204]

Answer:

C. 15

Step-by-step explanation:

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

\frac{x + 3}{x} = \frac{10 + 2}{10}

Solve for x

\frac{x + 3}{x} = \frac{12}{10}

\frac{x + 3}{x} = \frac{6}{5}

Cross multiply

5(x + 3) = x(6)

5x + 15 = 6x

15 = 6x - 5x

15 = x

x = 15
