To determine how many triangular bases are present among the 3 square pyramids and 2 pentagonal pyramids that Jayla sees, we need to analyze the types of bases on each type of pyramid:
-
Square Pyramids: A square pyramid has a square base. Therefore, it does not contribute any triangular bases.
-
Pentagonal Pyramids: A pentagonal pyramid has a pentagonal base. Similar to the square pyramid, it does not have any triangular bases either.
Since neither the square pyramids nor the pentagonal pyramids have triangular bases, the total number of triangular bases among the 3 square pyramids and 2 pentagonal pyramids is 0.
