[18x-15- (8x+1]/2)= 4x The angle is equal to half the difference of the arcs.\r
\n" ); document.write( "\n" ); document.write( "18x-15-8x-1=10x-16\r
\n" ); document.write( "\n" ); document.write( "(10x-16)/2=5x-8\r
\n" ); document.write( "\n" ); document.write( "5x-8=4x
\n" ); document.write( "x=8\r
\n" ); document.write( "\n" ); document.write( "4x=32, the angle desired.\r
\n" ); document.write( "\n" ); document.write( "The arcs are 129, the larger, and 65, the smaller.\r
\n" ); document.write( "\n" ); document.write( "Their difference is 64 degrees, and half of that (32 degrees) is the angle needed.
