not possible....how r u saying that??

arre...the 12 is the wind and 7 is the cyclist..

the angle between them is "NORTH EAST"

north + 0.5 * north to north east = 90 +45 = 135

arre...i am saying that the 135 degree position is incorrect...it shud be between 7 and 12....as the wind appears to come from north east for the cyclist.....so the angle is between the cyclist and the wind na?
