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.

Answer 1

Since ABCD is an isosceles trapezoid, the lengths of AB and CD are equal.

So, 7y - 4 = 8y - 18
Solving for y, we get:
y = 14

Therefore, the value of y is 14.
