Given ABCD is an isosceles trapezoid with
BC=9x+1 and AD=12x-11, find the value of x.
If the answer is 9, move to I
If the answer is 3, move to H
If the answer is 7, move to Y
If the answer is 4, move to T

Areflection of shape i across the y-axis, followed by a , and then a translation left 6 units and down 4 units confirms congruence between shape i and shape ii. alternatively, a of shape ii about the origin, followed by a reflection across the y-axis, and then a translation right 4 units and up 6 units confirms congruence between shape ii and shape i.
