Orville walks 270 m due east. He then continues walking along a straight line, but in a different direction, and stops 230 m northeast of his starting point. How far did he walk during the second portion of the trip and in what direction?
Please I need a good explanation for this, so there looking for magnitude and direction and I just cant seem to figure it out

The final distance from home is the hypotenuse (230m) of a right triangle with legs 162.63m. Thus, he ends up at point (162.63,162.63).
So, the final leg of his trip is the vector from (270,0) to (162.63,162.63). That is, (107.37,162.63), which is 194.87m in the direction 123.45 degrees (33.45 deg west of north)
