A) 8.3
B) 7.2
C) 9.6
D) 14.6

I have that the hypotenuse is 11. But I don't know if I should use the CAH or the SOH instead. I think its CAH. But I'm not sure.

Answer 1

You're right, it's CAH

Answer 2

Yay! Okay!! So would it be 11/x or how do I put that into like an equation to figure it out?

Answer 3

x=11cos41

Answer 4

This is how you know for sure if it's CAH or SOH.

Answer 5

Okay I think I put it wrong in my calculator. I ended up putting cos 11 and then cos 41. How do I put it in my calculator correctly?
