The measures of the angles of a triangle are shown below. Solve for x

Step-by-step explanation:

90+60+7x+12=180(sim of angles in a triangle)

7x+162=180

7x=180-162

7x=18

x=18/7

x=2.6

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 "
