Rain, pouring down at an angle alpha wit...

Rain, pouring down at an angle `alpha` with the vertical has a speed of 10 m/s. A girl runs against the rain with a speed of 8 m/s and sees that the rain makes an angle `beta` with the vertical, then relation between `alpha` and `beta` is

A

`tanbeta=(8+10sinalpha)/(10cosalpha)`

B

`tanbeta=(8+10cosalpha)/(10sinalpha)`

C

`tanbeta=(10sinalpha)/(8+10cosalpha)`

D

`tanbeta=(10cosalpha)/(8+10sinalpha)`
