Aboy rides a bike with a velocity of 6 m/s on a rainy day. the rain falls down with a velocity of 8 m/s. which direction should the boy hold the umbrella to protect himself from the rain? hint, set up a right triangle and find the angle using tangent formula below you will have to use second tangent on your calculator and make sure your calculator is in degrees a• 53.13° away from the horizontal position
b• 8° from the horizontal position
c• 36.87° away from the horizontal position
d• 48.59° away from the horizontal position

(A)

53.13° away from the horizontal position

Let's suppose boy rides a bike with a velocity of 6m/s in east

                  →

               6m/s

Let's suppose rain falls down with a velocity of 8m/s in north

                 ↓

               8m/s

Direction should the boy hold the umbrella to protect himself from the rain

                   /    x              ↓  

                /                       ↓

              → → → → → → → → →

                   6m/s

tanФ = opp / adj

tanФ = 8 / 6

tanФ = 4 / 3

tanФ = tan^-1(4 / 3)

tanФ = 53.13° from horizontal
