How many triangular bases are there among 3 square pyramids and 2 pentagonal pyramids that Jayla sees on her trip to Egypt?(1 point)
$$
The number of triangular bases can be calculated by adding the number of triangular bases of the square pyramids and the pentagonal pyramids.
Each square pyramid has 1 triangular base, and there are 3 square pyramids. So, the total number of triangular bases from the square pyramids is 1 triangular base per square pyramid * 3 square pyramids = 3 triangular bases.
Each pentagonal pyramid has 1 triangular base, and there are 2 pentagonal pyramids. So, the total number of triangular bases from the pentagonal pyramids is 1 triangular base per pentagonal pyramid * 2 pentagonal pyramids = 2 triangular bases.
Therefore, the total number of triangular bases is 3 triangular bases + 2 triangular bases = <<3+2=5>>5 triangular bases. Answer: \boxed{5}.
