Grade 11 math problem. 10 points best answer. Easy 10 points.?

Ah, yes. Because Pisa is north of the Tropic of Cancer, the sun at noon will be in the south. It won't be exactly in the south, but if we assume it is exactly south, the geometric construction will lie entirely in one plane.

We also have to assume that the ground the shadow falls along is level! Let the top of the tower = A Let the point on the ground under A = B Let the base of the tower = C Let the tip of the shadow = D Then ABC and ABD are right-angled triangles. Let the vertical height of the tower = z = AB Let the slant height of the tower = h = AC Let BC = x Then we have tan 84.5° = z/x tan 32° = z/(x + 84.02) Eliminating x, we get x = z/tan 84.5° x + 84.02 = z/tan 32° x = z/tan 32° - 84.02.

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.
