How Do You Calculate Displacement for Multiple Direction Movements?

Finding the displacement...

Okay so I've been having a lot of trouble trying to find the final displacement for a person who begins walking 200 meters west, the 300 meters south and finally meets his friend 150 meters away. I somehow got that he will be 80.5 degrees South or West by going Tan*(300m/80m) but I can't get his displacement as 58.3 meters...I'm confused. Help will be greatly appreciated :)

Opps the 150 meters where he meets his friend should be 150 meters east..

You sure it's 300 m south? You sure it's not 30 m?
