Elena says if the side that is 9 units is the base the height is 7.2 units. If the side that is 7.5 units is the base the corresponding height is 6 units. Noah says if the base is 9 units the corresponding height is 6 units. If the base is 7.5 units the corresponding height is 7.2 units. Do you agree with either one of them

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "

if you was gonna solve for a, a is a   < -12
