1.	Rain, pouring down at an angle alphawith 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 betawith the vertical, then relation between alpha and beta
Answer» `tan beta = (8+10 sin ALPHA)/(10 cos alpha)` `tan beta = (8+10 cos alpha)/(10 sin alpha)` `tan beta = (10 sin alpha)/(8+10 cos alpha)` `tan beta = (10COS alpha)/(8+10 sin alpha)` ANSWER :A
