hy here is ur answer:-
relative velocity of the rain drops wrt cyclist
= velocity of woman - velocity of rain
the magnitude of relative velocity the rain drops wrt woman
= √(12² + 35²) = 37 m/s
direction of relative velocity of the rain drops =
= tan⁻¹ (12/35) = 18.92 deg. from the vertical.
So the cyclist should hold the umbrella at 18.92 deg to the vertical in the forward direction.
hopes its help u
