Hey Dear,
◆ Answer -
θ = 53.13°
● Explanation -
# Given -
vr = 3 m/s
vm = 4 m/s
# Solution -
Velocity of man (horizontal) and velocity of rain (vertical) make right angle with each other -
tanθ = vm / vr
tanθ = 4 / 3
θ = taninv(4/3)
θ = 53.13°
Therefore, the rainfall makes angle of 53.13° with the vertical according to a stationary observer.
Hope this is helpful..
