PLEASE HELP AND PLEASE HURRY Let “n” represent the number of sides of any polygon and write an expression to represent the number of triangles that an n-gon can be divided into by using non-overlapping diagonals. (Hint: For each shape in the table, compare the number of sides in the polygon to the number of triangles, look for a pattern, and then write the expression.)

answer: x

step-by-step explanation:

chicken chicken chicken

step-by-step explanation:

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.

exactly you go it
