so, 5(root)3 would be your x coordinate then 5i would be your y

I guess you just have to work out roughly where 5(root)3 would be on your x axis

You can use the fact that there is a 306090 triangle involved. This means you can find the point exactly. Sound a bit complicated, so I'll try to make a drawing... (just hold on a sec!)

2 to the right, 1 up: a+bi corresponds to point (a, b)...
