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.
Since ABCD is an isosceles trapezoid, its legs AB and CD have the same length. Therefore:
7y - 4 = 8y - 18
Simplifying this equation, we get:
y = 14
Therefore, the value of y is 14.
