Please help me with Algebra 2. It's about radians and degrees.

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.

The perimeter of a movie screen is 54 meters. the screen is 18 meters wide. how tall is it?

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