Don't know if there's an easier way but you can use a box. Unlock the cursor lock first, activate cursor snap, select box and draw the box snapping to your line on that angle. Then, explode the box and erase unwanted lines.

I can think of three ways to do this ...

 

1/  Copy the line on the angle. Rotate the copied line and select the angle to rotate (90 degrees).

 

2/  Edit the line on the angle. Add 90 degrees to the number. Draw a new line and edit it to the new angle.

 

3/ Go to Draw > Options > Cursor Options > Pick Cursor Axis.  Click on the line which is on the angle and the cursor will rotate.

You can now draw a line perpendicular to it.

Press F11 to turn SNAP on, start anywhere you want and draw a line close to perpendicular. You will get a red symbol a small square within an "L" to show perpendicular, and it will then snap to the original line.

If I understand this correctly, I would use the offset command.  Click on the line, use the offset command (type O on my system) and offset distance you want.

This gives you a parallel line, not perpendicular although it's not a bad idea. If you offset your line and then turn snap on, you can draw a line either from the center to center of your 2 lines or the end points and that will give you a perpendicular line (90 degree) from your original line.

I use Steve's method #3. I use it so much that I even have the "Pick Cursor Axis" assigned to a shortcut key. Really quick to get a perpendicular line this way.
