1. The problem statement, all variables and given/known data:(adsbygoogle = window.adsbygoogle || []).push({});

Bob walks 360 m south, then jogs 490 m southwest, then walks 360 m in a direction 35 degrees east of north.

Use either trigonometry or components to find the displacement that will return Bob to his starting point by the most direct route. Give your answer as a distance.

Express your answer using two significant figures.

3. The attempt at a solution:

I drew a diagram and got the components of each.

360(cos35)(sin35)

490(cos35)(sin35)

For the components I got:

(0,360)

(401.38,281.05)

(294.89,206.49)

Then I added the x's and y's and used pythagoreum theorem, and I got d=1096.87, which isn't correct. What am I doing wrong??
