Question 977978
The sides of the 30-60-90 triangle 
are in the ratios: {{{ 1 }}} : {{{ sqrt(3) }}} : {{{ 2 }}}
( these are the sides opposite the respective angles )
[ side opposite 30 degree angle ] / [ side opposite 90 degree angle ]
= {{{ 1 / 2 }}}
---------------
Let {{{ a }}} = length of the short side
{{{ a / 50 = 1/2 }}}
{{{ a = 25 }}}
The length of the short side is 25
