What i need to know in this question is the answer

1.180

2.50

3.56

Step-by-step explanation:

M<4,M<2 and M<5 have to add up to 180 as a result of being a parallel line.

Making m<2 50 since 46°+84=130, 180-130=50.

Since m<1 is 74 and knowing m<2 is 50 74+50=124 180-124=56 m<3=56

Therefore 1,2,3 =180°

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 "
