I am having a lot of trouble with my homework. If anyone could help me, it would be much appreciated.(adsbygoogle = window.adsbygoogle || []).push({});

The Smith's go on vacation. They travel 16.0 km north/west; then turn 27 degrees to the left and go 135 km; then 294 km south/west. What is their displacement from home?

So I found the X and Y components (using trig functions) of each vector and added them. I then tried to put those numbers into the Pythagorean theorem, but it's not working. I think my X and Y components are wrong. I got the Xs to equal69and the Ys to equal155.3.This is the diagram I made: (the numbers that were given are in red, the rest I found, not sure if they are right though)
