hey guys, this is a particular type of question. I don't really know how to go about solving questions that mention an angle.

Example:
Find the gradient of the straight line:
i) Perpendicular to the line making an angle of 120 degrees with the x-axis in the positive direction

Can someone simply explain how this works? All the other questions involving this I have no issues with, but if it mentions making an angle, I get stumped.

Cheers :)
