This is the question i put it on another post but it did not have a photo

I would chose the third answer choice.

You can set up 60/5 as part of the proportion because those sides of the triangle correspond to one another. 12 and the unknown side length correspond to one another as well, so you can use 12/x as the other part of the proportion. X would represent the missing side length.

It is a percent with money involved too divide and you should have your answer
