Arock breaks loose from a cliff and plunges toward the ground 400 feet below. the distance "d" that the rock falls in "t" seconds is given by the equation d=16t^2. how long does it take the rock to hit the ground?

Will give are given that xy is parallel to zw. if xz is a transversal that intercepts xy and zw, angle angle alternate interior angles. since xy is parallel to zw, we know that these angles are we also know that angle xvy and angle zvw are , and thus congruent. we can conclude that △xyv ~ △zwv using the similarity theorem.
