4.99 units

Step-by-step explanation:

Considering ∆ABD in the figure given, <ABD = <ABC = 90° (angle on a straight line)

Therefore, we would consider ∆ABD as a right angled triangle having side AB = 3 units, and angle D = 31°

==>Use trigonometric function to solve for the length of side BD

Side BD is the adjacent side to the angle given, while side AB is the opposite side to the angle given.

Thus,

tan D = opposite/adjacent

tan 31 = 3/BD

0.6009 = 3/BD

multiply both sides by BD

0.6009*BD = 3

Divide both sides by 0.6009 to make BD the subject of formula

BD = 3/0.6009

BD ≈ 4.99 units

4.99 is correct took the test

Step-by-step explanation:

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "
