Question

ABCD is an isosceles trapezoid with legs Modifying above upper A upper B with barand modifying above upper C upper D with barand base modifying above B C with bar. If the length ofModifying above upper A upper B with baris 7y – 4, the length of modifying above B C with bar is 4y – 6 and the length of modifying above upper C upper D with baris 8y – 18, find the value of y.

Answer 1

C i am prettie sure

Answer 2

its only an open writing type of question, it doesn´t show answers:(

Answer 3

oh ummmmmm hang on

Answer 4

do u have any gusee

Answer 5

We are told that the legs of the isosceles trapezoid are AB and CD

AB = 7y - 4
CD = 8y - 18

In any isosceles trapezoid, the two legs are of equal length.
Therefore, AB = CD

⇒ 7y - 4 = 8y - 18

Add 18 to both sides of the equation
7y - 4 + 18 = 8y - 18 + 18
7y + 14 = 8y

Subtract 7y from both sides of the equation
7y - 7y + 14 = 8y - 7y
14 = y
⇒ y = 14

Answer 6

WOW! I couldn´t figure that out if I even tried

Answer 7

C
