Next time you post, be sure to post the instructions.  
I will assume the instructions are this:

<font face = "Times new roman">In the following, the first two numbers or question marks represent
the legs of a right triangle and the third number or question mark
represents the hypotenuse of that right triangle.  Give numbers
for all the question marks.</font>


1) a=6 b=8 c=? 

{{{c^2=a^2+b^2}}}
{{{c^2=6^2+8^2}}}
{{{c^2=36+64}}}
{{{c^2=100}}}
{{{c=sqrt(100)}}}
{{{c=10}}}

2) a=? b=12 c=13 

{{{c^2=a^2+b^2}}}
{{{13^2=a^2+12^2}}}
{{{169=a^2+144}}}
{{{25=a^2}}}
{{{a^2=25}}}
{{{a=sqrt(25)}}}
{{{a=5}}}


3) a=? b=4 c=5 

{{{c^2=a^2+b^2}}}
{{{5^2=a^2+4^2}}}
{{{25=a^2+16}}}
{{{9=a^2}}}
{{{a^2=9}}}
{{{a=sqrt(9)}}}
{{{a=3}}}

4) 9 21 ? 

{{{c^2=a^2+b^2}}}
{{{c^2=9^2+21^2}}}
{{{c^2=81+441}}}
{{{c^2=522}}}
{{{c=sqrt(522)}}}
{{{c=sqrt(9*58)}}}
{{{c=sqrt(9)*sqrt(58)}}}
{{{c=3*sqrt(58)}}}

5) 24 10 ?  

{{{c^2=a^2+b^2}}}
{{{c^2=24^2+10^2}}}
{{{c^2=576+100}}}
{{{c^2=676}}}
{{{c=sqrt(676)}}}
{{{c=26}}}


6) ? 3 4

{{{c^2=a^2+b^2}}}
{{{4^2=a^2+3^2}}}
{{{16=a^2+9}}}
{{{7=a^2}}}
{{{a^2=7}}}
{{{a=sqrt(7)}}}
