**Resultant Force: Something I am messing up on in calculation - ?**

## Homework Statement

Hey all,

This is a resultant force word problem. I will just post the my answer and the problems answer. I have no idea why there is a different answer here.

**Correct:**R^2=1500^2+2300^2 - 2 x 1500 x 2300 Cos(138)

**Correct Answer**= R = 3559.2 Newton

My answer is WAYYY off, so there is something I am missing here...

By the way, I am using the TI-89 Titanium

Thanks for any help!
