You have not understood the question
One ball is released from point D, which will reach point C in some time.
One more ball is released from point A and will travel down the slope to reach point C. The question is to calculate H (height) i.e distance between D and C so that both ball reaches point C at the same time

shvmgupta2002p7q02w: ok

PunitB: is it H = h*cot(theeta)*(1+cot theeta)

shvmgupta2002p7q02w: nope.....

PunitB: h*cot theeta*(1+cosec theeta)

PunitB: have added file...please chk

shvmgupta2002p7q02w: ???

shvmgupta2002p7q02w: kuch smjh nai aaya.

shvmgupta2002p7q02w: mein total time for ball 2 k lie ab and bc divide krke nikala hu
