Question 1030631
Picture an isosceles right triangle for starters...the sides of the triangle are 8/sqrt(2) = 4*sqrt(2).  But that is a 90 degree angle...you need a touch less...would make the sides a touch bigger...
{{{4*sqrt(2) = 5.6568}}}
so to the nearest tenth, the sides would have to be 5.7 cm each.
