In the triangle shown, find the length of the hypotenuse. If this question doesn’t get answered I’m gonna be stressed out even more. I don’t know any of the answers to any of these questions.

Can you me with this question? i'll reward *30 points i just need with this one question so that i could solve the others. * edit: i originally set up the question to reward 30 points, but for some reason i can only reward 15. if you don't get 30, then i'm sorry. i'm still kind of new to this site
