Question 187984: I have a question.
A water slide is a straight ramp 25 m long that starts from the top of a tower 21 m high. Find the angle the slide forms with the tower (to the nearest degree).
So, I'm not sure if I am even on the right track, but I used the Pythagorean Theorem to get the last side. I got 2 sqare root of 46. But I don't even know if that is right or if I need to use that. So, I still don't know how to find the angle of the slide with the tower.
Thanks a lot for answering
