When two lines intersect as in the illustration below, four angles are formed. Angles that are side-by-side, such as

\angle 1

and

\angle 2

, are called adjacent angles. Angles that are nonadjacent, such as

\angle 1

and

\angle 3

\angle 2

and

\angle 4

, are called vertical angles. From geometry, we know that if two lines intersect, vertical angles have the same measure. If

m ( \angle 1 ) = ( 5 x + 10 ) ^ { \circ }

m ( \angle 1 ) = ( 5 x + 10 ) ^ { \circ }

and

m ( \angle 3 ) = ( 7 x - 10 ) ^ { \circ }

, find x . Read

m ( \angle 1 )

as "the measure of

\angle 1

". $When two lines intersect as in the illustration below, four angles are formed. Angles that are side-by-side, such as \angle 1 and \angle 2 , are called adjacent angles.
