Explanation:
given
speed of rain=35m/s
speed of wind =12m/s
=√(12^2+35^2)
=37m/sec
the direction of the resultant velocity vector with the vertical
=tan^-1(12/35)
=18.92°
the umbrella should be pointed in the direction opposite to the resultant velocity of the raindrops.so it Should be in the direction of 18.92°.
I hope it is helpful..
