Seth is using they figured some below to prove the pythagorean theorem using triangle similarity in the given triangle DEF , angle D is 90 degree and segment DG is perpendicular to segment EF

part A: identify a pair of similar triangles
Part B: explain how you know the triangles from part A are similar
part C: if EG =2 and EF=8 find the length of segment ED show work ​

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 "

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
