The PCGCC prides itself on its "nouveau" architecture. In particular, one of the reception halls is a glass pyramid. The pyramid looks like two tetrahedrons pasted together: it has four sides and a square base. It was constructed according to the following equations. x+y+ 21 :=1, with x, y, and z 20 10 1 z=1, with-x, y, and z 20 10 21 1 N=1, with x, -y, and z 20 21 1 1 z=1, with-x, - y, and z 20 21 a) Draw the reception hall on a 3-dimensional Cartesian coordinate system. b) Determine the height of the reception hall.
