Abcd is an isosceles trapezoid with legs ab & cd and base bc if the length of ab is 7y-4 the length of bc is for 4y-6 and the length of cd is 8y -18 find the value of y

The value of y is 14.

Step-by-step explanation:

Given,

Length of AB =

Length of BC =

Length of CD =

Since ABCD is an isosceles trapezoid then according to property of trapezoid which is given below;

"In any isosceles trapezoid, two opposite sides (the bases) are parallel, and the two other sides (the legs) are of equal length."

So Length of AB = Length of CD

Hence the value of y is 14.

answer is x<
