Question 1153124
Let the length = {{{ x }}}
{{{ 15^2 + x^2 = 36^2 }}}
{{{ 225 + x^2 = 1296 }}}
{{{ x^2 = 1296 - 225 }}}
{{{ x^2 = 1071 }}}
{{{ x = 32.726 }}}
---------------------
The approximate length is 32.7 inches
---------------------
check:
{{{ 225 + x^2 = 1296 }}}
{{{ 225 + 32.726^2 = 1296 }}}
{{{ 225 + 1071 = 1296 }}}
{{{ 1296 = 1296 }}}
OK
