Web1 Answer. Sorted by: 1. Take z axis up, and the base of the pyramid aligned with the x and y axes. I think you mean that one side plane has a normal vector n = ( 0, cos ( 25 ∘), sin ( 25 ∘)), and an adjacent side plane has normal m = ( cos ( 25 ∘), 0, sin ( 25 ∘)). Then the cosine of the angle between the perpendiculars is the dot product. WebWHAT'S YOUR ANGLE? Answer the two questions below. How many acute angles are in a pyramid?
