In triangle ABC, side AB measures 3 cm, side BC measures 5 cm, and side AC measures 7 cm. The measures of the angles are 21.8º, 38.2º, and 120º. What could the measure of angle A be? 21.8º 38.2º 120º answer is 38.2

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.
