To solve the problem, we first need to understand the bases of the pyramids mentioned:
- A square pyramid has a square base.
- A pentagonal pyramid has a pentagonal base.
Jayla sees:
- 3 square pyramids
- 2 pentagonal pyramids
Now, we need to determine the number of triangular bases among these pyramids.
Since neither the square pyramids nor the pentagonal pyramids have triangular bases, we conclude that:
- Square pyramids contribute 0 triangular bases.
- Pentagonal pyramids also contribute 0 triangular bases.
Therefore, the total number of triangular bases from the pyramids Jayla sees is:
\[ 0 + 0 = 0 \]
Thus, the number of triangular bases among the pyramids is 0.
