find the side length of a 15-sided regular polygon with apothem a=6 and area A= 282 square inches.
\n" ); document.write( "----------------
\n" ); document.write( "Central angle = 360/15 = 24 degs
\n" ); document.write( "Each of the 15 segments can form 2 right triangles with the apothem and the side, and the angles at the center are 1/2 of 24 deg = 12 degs.
\n" ); document.write( "-----------
\n" ); document.write( "(s/2)/a = tan(12)
\n" ); document.write( "s = 2*a*tan(12)
\n" ); document.write( "s =~ 2.5507
\n" ); document.write( "
