How can I draw scaled vector diagrams for given vectors?

[allielove13]

I'm confused about how to draw scaled vector diagrams. I have a scale and I can do the first two vectors, but then I get confused.
Let's say my vectors are 10 cm at 0 degrees, 5 cm at 45 degrees, and 11 cm at 212 degrees.
How do I draw this? I have this:

Ok, you see at the point where you began to draw the 10? Measure all the angles from that point. Draw the 45 from there and draw the 5 cm.

For the 212, remember that when measuring the angles we measure counter-clockwise, so measure 212 degrees counter clockwise from that point. Are you able to do this one?
