Question 935918
triangle has to be right angle triangle to solve this problem
length (AB) = 19 in
length(BC) =24 in
as per Pythagorean theorem
   {{{ AB^2+BC^2=AC^2}}}}
        {{{19^2+24^2=AC^2}}}
        {{{361+576=AC^2}}}
         {{{837=AC^2}}}
             square root on both sides
 {{{ sqrt(837)=sqrt(AC^2)}}}
     {{{ 28.93 =AC}}}
Result: AC  =28.93 in
