Question

I’m confused on this one

Answer 1

For this, you will be using proportions. And in this case, the proportion will be $\frac{5}{6} =\frac{x+4}{x+6}$

Firstly, cross-multiply: $5x+30=6x+24$

Next, subtract 5x on each side: $30=x+24$

Lastly, subtract 24 on each side, and your answer will be 6 = x

To find BC, just add 4 and 6 together, which is 10. And to find AC, add 10 and 2 together, which is 12.

In short, the answer is the first option.
