For the question you mentioned which was answered by Chris and Harley I use the NSided Pyramid tool on the Compound Angle Calculator page with the number of sides equal to 6, the base radius of 13 inches and the height of 5.2 inches the Compound Angle Calculator gave a bevel angle of 12.1 degrees. Notice that in our solution we reported the complement, 77.9 = 90  12.1. Penny
