Question 564641
Imagine the side that is {{{ 37 }}} laying flat
on a table. The side that is {{{ 35 }}} is hinged
at one end of the {{{ 37 }}}. It is free to swing
in a plane that is perpendicular to the table.
-----------------------------------
If you lay it alongside the {{{ 37 }}} side, the 
difference is {{{ 2 }}}, so {{{ x > 2 }}} is one limit.
-----------------------------------
As I swing the {{{ 35 }}} side I must stop before
the distance from the free end of {{{35}}} and
the unhinged end of {{{37}}} equals {{{ 35 }}},
because {{{x}}} must be the shortest side
-----------------------------------
So, the limits are {{{ 2 < x < 35 }}}
Hope this isn't confusing
