Answer 1

\frac{8}{10} =\frac{x}{5} to solve for x.

Answer 2

Since the triangles are similar, they will have proportional sides. With this knowledge, we can make the proportion $\frac{8}{10} =\frac{x}{5}$ to solve for x.

Firstly, cross multiply: $40=10x$

Next, divide by 10 on both sides, and your answer will be 4 = x, or the first option.
