**Damon**, Monday, June 20, 2011 at 8:04pm3 isosceles triangles around circle center with equal legs of 21 in and included angle of 360/3 = 120 degrees

other 2 angles are (180-120)/2 = 30 deg

law of sines

sin 120/base = sin 30/21

.866/base = .5/21

so base, which is a side of our triangle = .866 *21 * 2 = 36.4 in
