All Quadrilateral has an angle sum of 360. you know, that diagonals divides an angle into two the same angles. Also, you should know that opposote angles of the rhombus is equal. so you need to solve this: 2x+2(3x-26)+2x+2(3x-26).

flutter, i forgot to add 360! the eq is this: 2x+2(3x-26)+2x+2(3x-26)=360

8(2x-13)?

OpenStudy (kamille):

4x+6x-52+6x_52=360 16x=464 x=29
