let one angle be $\"x\"$ °
\n" ); document.write( "adjacent angle is $\"2x-15\"$ °\r
\n" ); document.write( "\n" ); document.write( "sum:
\n" ); document.write( " $\"x+%2B+2x-15+=+180\"$ °\r
\n" ); document.write( "\n" ); document.write( " $\"3x+=+180%2B15\"$ °\r
\n" ); document.write( "\n" ); document.write( " $\"3x+=+195\"$ °\r
\n" ); document.write( "\n" ); document.write( " $\"x+=+65\"$ °-> one angle\r
\n" ); document.write( "\n" ); document.write( " $\"2x-15\"$ °=> $\"2%2A65-15\"$ °=> $\"115\"$ °->the angle next to it\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
