Help...

page 18 says: 1. Beginning at the center of the cul-de-sac of Ocean Ave, travel 50 feet at a bearing of s15dw to the PC. THE CENTERLINE THEN CURVES TO THE LEFT. ITS RADIUS IS 85 FEET AND ITS DELTA ANGLE IS 97D. THE CENTERLINE THEN TRAVELS 185 FEET.

 

The part in uppercase is what I am struggling with.

I have tried drawing a const. line from PC @85

Then draw arc using start from PC>Center>angle:97.

Everytime I type in the 97 for the angle it gives me an "Invalid" error.

 

I am truly struggling and just cannot seem to find a way to do this centerline....anyone to help out there???
