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.
(2 points)
In an isosceles trapezoid, the legs (AB and CD) are congruent.
Given that AB = 7y – 4 and CD = 8y – 18, we can set up an equation:
7y – 4 = 8y – 18
Subtracting 7y from both sides:
-4 = y – 18
Adding 18 to both sides:
14 = y
Therefore, the value of y is 14.
