Notice that angle a is located where two lines cross. Two angles are equal where two lines cross. In other words, vertical lines are congruent. So, the measure of angle a = 110 degrees.\r
\n" ); document.write( "\n" ); document.write( "Angle b = 180 degrees - 130 degrees\r
\n" ); document.write( "\n" ); document.write( "Where did 180 come from? It is the measure of a straight line. Angle b lies on a straight line. See it?\r
\n" ); document.write( "\n" ); document.write( "Angle b = 50 degrees
