statement:--------------------------------- reasons:
\n" ); document.write( "Ray \"AC\" bisects \n" ); document.write( "\"m\" < \"BAC+=+13x\"------------------- (Given)
\n" ); document.write( "\"m\" < \"CAD+=+6x+%2B+21\"--------------also ****GIVEN ****
\n" ); document.write( "\"m\" < \"BAC\" = \"m\" <\"CAD\"------------------- Definition of angle bisector
\n" ); document.write( "\"13x+=+6x+%2B+21\"------------------- SUBSTITUION OF VALUES
\n" ); document.write( "\"13x+-+6x+=+6x+-+6x+%2B+21\"------------------- Addition/Subtraction Property
\n" ); document.write( "\"7x+=+21\"------------------- Substitution Property
\n" ); document.write( "\"7x%2F7+=+21%2F7\"------------------( MULTIPLY BOTH SIDES BY \"1%2F7\")-Multiplication Property of Equality
\n" ); document.write( "\"x+=+3\"------------------- Substitution Property
