Find the value of x that makes the parallelogram a rectangle.
\n" ); document.write( "A parallelogram has one angle labeled 5 x plus 15 degrees.
\n" ); document.write( "----
\n" ); document.write( "Each angle of a rectangle is 90 degrees.
\n" ); document.write( "----
\n" ); document.write( "Solve::
\n" ); document.write( "5x + 15 = 90
\n" ); document.write( "5x = 75
\n" ); document.write( "x = 15
