When two lines intersect as in the illustration below, four angles are formed. Angles that are side-by-side, such as and , are called adjacent angles. Angles that are nonadjacent, such as and or and , are called vertical angles. From geometry, we know that if two lines intersect, vertical angles have the same measure. If and , find x .
