having problems figuring out how to draw this curve, if anyone can help it would be greatly appreciated!

 

Here is the description......

 

North 41d15'38" East, a distance of 39.45 feet (here is where my problems begin) to the beginning of a non-tangent curve concave northwesterly and having a radius of 1560.00 feet; from which beginning of curve the radius point bears North 07d37'40" West

 

Thanks if anyone can help!

Yes, from the pc, go the bearing shown and radius.  Then turn the cental (delta)angle and go back up the radius distance.  

That will then give you the beginning, ending and radius of the curve so you can draw it.  The curve will not be tangent to the straight sections.
