How many different rows can the array have if the multiple is 4

Me write an equation for the interior angles of this triangle that uses the triangle sum theorem

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.

He that is measured at 220° is a reflex angle. the opposite angle is obtuse. find the measure of obtuse .
