Analyze the diagram below and complete the instructions that follow. find the value of a. a.3 b.5 c.8 d.12

option A. 3

Step-by-step explanation:

AS shown for the fight angle triangle

12² = 18 * (a+5)

a + 5 = 12² /18 = 144/18 = 8

a = 8 - 5 = 3

So, the answer is option A. 3

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 "

62.5 paisa

step-by-step explanation:

4000*70 = 280000

280000-(2000*90) = 100000

4000-2400 = 1600

100000/1600 = 62.5
