Question 1067105
All you need to draw is the {{{ 95 }}} ft tall 
center pole and the line from the top to
the ground. At a point {{{ 96 }}} ft from the
center pole drop a {{{ 49 }}} ft vertical line to the ground.
--------------------------------------------------
Call the distance from the last row of seats to the point
where the rope is staked {{{ d }}}
-------------------------------
There are similar triangles
{{{ 95 / ( 96+d ) = 49/d }}}
Multiply both sides by {{{ d*( 96 + d ) }}}
{{{ 95d = 49*( 96 + d ) }}}
{{{ 95d = 4704 + 49d }}}
{{{ 95d - 49d = 4704 }}}
{{{ 46d = 4704 }}}
{{{ d = 102.26 }}}
and
{{{ 96 + 102.26 = 198.26 }}}
{{{ .26*12 = 3.12 }}}
The ropes should be staked 198 ft 3 inches away from center pole
-------------------------
check:
{{{ 95 / ( 96+d ) = 49/d }}}
{{{ 95 / ( 96+102.26 ) = 49/102.26 }}}
{{{ 95 / 198.26 = 49/102.26 }}}
{{{ .4792 = .4792 }}}
OK
