Explanation:

Step1: Recall net - concept

A net of a triangular pyramid is a 2 - D shape that can be folded to form the 3 - D triangular pyramid. A triangular pyramid has 4 triangular faces.

Step2: Match face - lengths

Check the lengths of the sides of the triangles in the net with the lengths of the sides of the given triangular pyramid. The base of the given triangular pyramid is an equilateral triangle with side - length 16 ft and the other three triangular faces have sides with lengths 14 ft and 16 ft.

Step3: Analyze options

Analyze each of the provided net diagrams. The correct net should have four triangles that can be folded to match the given pyramid's shape and side - lengths. The first net diagram has four triangles and the side - lengths match the given triangular pyramid's side - lengths.

Answer:

The first net diagram (the one on the left)
