Since ABCD is an isosceles trapezoid, the legs AB and CD are congruent. This means that their lengths are equal. Therefore, we can set up the equation 7y – 4 = 8y – 18.
Simplifying the equation, we have -4 + 18 = 8y – 7y.
This gives us 14 = y.
Therefore, the value of y is 14.
ABCD is an isosceles trapezoid with legs AB and CD and base BC . If the length of AB is 7y – 4, the length of BC is 4y – 6 and the length of CD is 8y – 18, find the value of y.
