If a 40-foot tree casts a 12-foot shadow, find the length of the shadow cast by a 22-foot tree.
The length of the tree's shadow is
feet.

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.
