The Attempt at a Solution



Well I originally thought I could draw a graph where x=6 and y=...then I realized i was solving for y. I don't know what the magnitude bit means. I thought it meant direction, but I don't see how that applies or would help me solve the problem. A little advice on how to solve this problem would be lovely!

Treat this as a right angle triangle

The magnitude would be the hypotenuse in this case
