Question

Find the value of x in the figure below

Answer 1

we're assuming these are 2 SIMILAR triangles, thus the only difference between is the RATIO or PROPORTION, thus
$$
\cfrac{x}{14}=\cfrac{10}{8}\\
$$
then just solve for "x" to get your ratio

Answer 2

well, not the ratio, the side length in this case

Answer 3

@jdoe0001 I still don't know how to solve it though :( I'm horrible at math and have been working on this like all day.

Answer 4

well, ahemm if you multiply both sides by 14
$$
\cfrac{x}{14}=\cfrac{10}{8}
\implies
\color{blue}{(14)}\cfrac{x}{14}=\cfrac{10}{8}\times\color{blue}{(14)} \implies ?
$$
what would that give you?

Answer 5

@jdoe0001 I got 17.5, is that right or did I do it wrong?

Answer 6

that's what I got, yes

Answer 7

Thank you! :)
