A) 2b²=100 b²=100/2 b²=50 b=raiz(50) c) 8²+AB²=16² AB=raiz(16²-8²) AB=raiz(192) altura h h²+ (16-m)²=raiz(192)² h²+m²=8² destas duas equacoes resolvemos em ordem a h² e igualamos h²=192-(16-m)² h²=64-m² igualando fica 192-(16-m)²=64-m² -(256-32m+m²)+m²= 64-192 -256+32m-m²+m²=-128 32m=-128+256 32m=128.
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.
