Question 998005
Sides a and b are known.
Side c is unknown.
Sides a and b must be the legs and side c is the hypotenuse.  These leg and hypotenuse assumptions are because you did not give the problem description but indicate only that you have two sides of a right triangle.


The way the description was described here,  {{{a^2+b^2=c^2}}}.
If you want a finished solution for c, then, "Solve for c by taking the square root of both sides".  This is already clear.


{{{c*c=c^2}}} and you want c.


{{{(something)(something)=a^2+b^2}}} and you want to have that {{{something}}}.
