## Homework Equations

**well I figure my scout troop made a right triangle and I need to put it into a^2+b^2=c^2 I've got 1.3^2 + b^2= 3.7^2 after all the math I get 12 and square root that and you've got 3.46 but apparently that's wrong and I don't know how else to solve it. I really don't get these at all so if anyone can help me add vectors (feel like an idiot I'm 30 and can't add) I'd appreciate it.**
