A ladder 20 feet long leans against the wall of a house. The base of the ladder is pulled away at a rate of 3?

X = distance from wall to bottom of ladder sin T = 7/25 cos T = 24/25 T = angle theta sin T = x/25 x = 25 sin T dx/dt = 25 cos T dT/dt 2 = 25 (24/25) dT/dt = 24 dT/dt dT/dt = 1/24 = 1/12 = 0.0833333 rad/sec.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
