First of all, this problem has nothing to do with Trigonometry. You are more likely to get a faster response to your posts when you post in an appropriate category.

\n" ); document.write( "This problem can be solved with...
  • Two variables:
    \n" ); document.write( "Let x = one leg
    \n" ); document.write( "Let y = the other leg
    \n" ); document.write( "Then
    \n" ); document.write( "x + y = 7
    \n" ); document.write( "And the three sides must fit the Pythagorean equation:
    \n" ); document.write( "\"x%5E2%2By%5E2+=+5%5E2\"
    \n" ); document.write( "Now just solve this system of equations. (I suggest the Substitution Method.
  • One variable:
    \n" ); document.write( "Let x = one leg
    \n" ); document.write( "Then the other leg is: 7-x
    \n" ); document.write( "And the equation we will use is the Pythagorean equation:
    \n" ); document.write( "\"x%5E2+%2B+%287-x%29%5E2+=+5%5E2\"
    \n" ); document.write( "Now just simplify and solve.
