C) Complementary, x = 12

Step-by-step explanation:

This angles are complementary because they add up to 90 (because of the square in the corner)

4x + 1 + 4x - 7 = 90

8x - 6 = 90

8x = 90 + 6

8x = 96

x = 12

complementary; x=12

Step-by-step explanation:

two angles who form a right angle (90°) are complementary. so,

90° would equal those two angle measures added together. make an equation then simplify.

90 = (4x+1) +(4x-7)

90 = 8x - 6

+6 +6

96 = 8x

÷8 ÷8

x = 12

because 1.2 isnt half of 6 duh

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 "
