the avrage diameter of a tree is measured over time. the equation y=3/4x, where x is time in years and y is the diameter in inches, models the relationship what is the predicted diametter in inches of the tree after 12 years?

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.
