Homework Statement

:[/B]

Draw the vectors:
A.) 60 lbs at 25 degrees east of north.
B.) 40 lbs at π/3 south of west.

Homework Equations

I've tried different things but keep getting the wrong answer. Can someone please explain how to solve these types of problems?

The Attempt at a Solution

I drew a graph, made 1 represent 10 lbs, 2 represent 20 lbs, etc. and drew a line to 6 (60 lbs) and then raised it to a 25 degree angle, but I keep getting the wrong answer.

It is not clear exactly what you did from your description. Could you perhaps provide an illustration?

Did you draw a line segment of length 6 pointing east, then rotate it 25 degrees to the north? (That is what is sounds like, when you say "raise it to a 25 degree angle".) However, the problem requires you to draw a line of length 6 pointing north, then rotate it 25 degrees to the east (so it points 25 degrees east of north).

Yes! That's what I was doing! Thank you so much for the guidance. There were two questions like this with two parts each and I did them all right after reading your reply! Thanks again :)
