ΔABC ≅ ΔEDC by the SAS postulate.

<h3>What is the SAS postulate's conclusion?</h3>

Postulate of Side-Angle-Side (SAS) ,The two triangles are said to be congruent if two sides and the included angle of one triangle match those of another triangle by two sides and the included angle.

According to the SAS Postulate, two triangles are congruent if their two sides and included angles are identical to those of another triangle's two sides and included angle

The midpoint of DB and AE Given is at C.

BC ≅ CD Two equal portions are produced by the midway C.

AC ≅ CE Two equal portions are produced by the midway C.

ACB and DCE Congruent vertical angles exist.

By the SAS postulat, ABC becomes EDC.

Please please help I really need it today please show work
Cerrena [4.2K]

Answer:

<u><em>x=9</em></u>.

<em><u>perimeter=68</u></em>

<em><u>area=168</u></em>

Step-by-step explanation:

First find the side that has a exact number which would be the bottom 28cm then look at the opposite side (2x+10) in order to find x subtract 10 from 28 which gives you 18, now 2x means x multiplied by 2 so what multiplied by 2 = 18? 9 meaning <u><em>x=9</em></u>. Now you are going to want to plug 9 in to your short side (x-3) once you plug it in it should look like this 9-3 and 9-3=6 meaning the short side is 6cm. In order for you to find the perimeter you have to add the sides together so 28+28+6+6 wich <u><em>=68</em></u> and in order for you to find the area you have to  multiply the length and the width so 28x6 which is <em><u>168</u></em>.

hope that helped :)
