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
`(8)/(10) =(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.
