Answer 1

in west to east direction.

== √(12²+35²) = 37 m / sec

..so the diretion of resultant velocity vector must be with the verrtical that is tan theta inverse = 18.92 deg.

so umbrella should be pointed in direction oppo. to the reusltant velocoty of rain drops..

so it should be in 18.92 inclination towards east ...
