An engineer is designing a roof for a gazebo in the shape of a regular hexagon with a 8-foot diagonal that passes through the center of the polygon. What is the length of the apothem of this polygon? Round your answer to the nearest tenth of a foot.

(40 points) i need some . an answer definition is appreciated as well.

An equation of the line tangent to y=x^3+3x^2+2 at its point of inflection is

Given: ae ≅ ce ; de ≅ be prove: abcd is a parallelogram. we have that ab || dc. by a similar argument used to prove that △aeb ≅ △ced, we can show that △ ≅ △ceb by. so, ∠cad ≅ ∠ by cpctc. therefore, ad || bc by the converse of the theorem. since both pair of opposite sides are parallel, quadrilateral abcd is a parallelogram.
