Rain is falling vertically downward with speed of 35 m/s.
Wind starts blowing from East to West with speed of 12 m/s.
Horizontal component of rain = 12 m/s (towards West)
Vertical component = 35 m/s (downward)
Tan θ = 12/35
θ = tan−1 (12/35) ≈ 19°
Therefore, the boy should tilt the umbrella about 19° from the vertical towards the east to avoid the rain.
