Hmm, it says 'how long is the ramp.'
I'm not sure if it would be the hypotenuse or the other leg. :l

Okay. Can we try this question then?

A ladder is leaning against a building, forming a 70° angle with the ground. The base of the ladder is 8.2 ft from the base of the building.

 What is the length of the ladder?

That looks right. Do you know a trignometric function we can use to solve the hypotenuse, which is the length of the ladder?
