Question 860593
a man is going towards east v=36km/hr and the wind is blowing towards north with v=18km/hr.The wind appears to the man with angle?
--------
Relative wind from the east at 36 km/hr 
--> vector magnitude 36, terminal point (-36,0)
towards north with v=18km/hr
--> vector magnitude 18, terminal point (0,18)
Translate to (-36,18)
=================
Resultant vector is the hypotenuse.
{{{Magnitude = sqrt(36^2 + 18^2)}}}
Direction = atan(-36/18)
= 116.56 degs
-----
Relative to the man facing east = 116.56 - 90 degs
= 26.56 degs off center to his right
