Solve for x. Round to the nearest tenth of a degree, if necessary.

x=28.8

Step-by-step explanation:

using cosine

cos x= adjacent/hypotenuse

cos x = 71/81

cos x = 0.8765

make x subject of the formula

x= cos^-1 0.8765

x= 28.77699973

x≈ 28.8

i can you with this question sweetie!

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 "
