Light pole brain teaser

You are in a parking lot with poles oriented something like this. It's a freehand drawing, so measurements are not accurate. You have 50 feet of parachute line plus enough to tie it to the pole.

Using a compass and the parachute line, draw the azimuth lines and distances shown.

Do not go outside the 50 foot circle.

(This is a tough one.)

Time limit: 1 hour.

Accuracy:

No more than 8 feet error on any distance or 5 degree error on any bearing.

.

To solve it, I used this diagram. The vetical scales and horizontal scales are not the same wideth. Just a problem with Exel I'll work on.
