document.write( "Question 1102091: Kelly is mountain climbing with Jenny and has just climbed a 6-meter vertical rock face. Jenny is standing at the bottom of the cliff, looking up at Kelly. If Jenny is 9 meters away from Kelly, how far away from the cliff is Jenny standing? If necessary, round to the nearest tenth. \n" ); document.write( "

The distance from Kelly to Jenny is
\n" ); document.write( "the hypotenuse, \"+c+\", of a right triangle.
\n" ); document.write( "\"+c+=+9+\" m
\n" ); document.write( "Let the height that Kelly has climbed = \"+a+\"
\n" ); document.write( "\"+a+=+6+\" m
\n" ); document.write( "Let the distance from Jenny to the cliff = \"+b+\"
\n" ); document.write( "---------------------
\n" ); document.write( "Use the pythagorean theorem
\n" ); document.write( "\"+a%5E2+%2B+b%5E2+=+c%5E2+\"
\n" ); document.write( "\"+6%5E2+%2B+b%5E2+=+9%5E2+\"
\n" ); document.write( "\"+36+%2B+b%5E2+=+81+\"
\n" ); document.write( "\"+b%5E2+=+81+-+36+\"
\n" ); document.write( "\"+b%5E2+=+45+\"
\n" ); document.write( "\"+b+=+sqrt%28+45+%29+\"
\n" ); document.write( "\"+b+=+3%2Asqrt%28+5+%29+\"
\n" ); document.write( "\"+b+=+3%2A2.236+\"
\n" ); document.write( "\"+b+=+6.708+\"
\n" ); document.write( "Jenny is 6.708 m from the cliff
\n" ); document.write( "-----------------------------
