Start with the given line segment\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"Photobucket\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Draw a line straight down from the right end of the line segment\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"Photobucket\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "From that point, draw a horizontal line to the left end of the line segment. Notice how a right triangle is formed.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"Photobucket\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "From the picture, we can see that the triangle has legs of 2 and 3 and an unknown hypotenuse (which is the length of the line segment)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"Photobucket\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Since we can see that the triangle has legs of 3 and 2 with a hypotenuse of x, we can use Pythagoreans theorem to find the unknown side.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Pythagoreans theorem:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"a%5E2%2Bb%5E2=c%5E2\" where a and b are the legs of the triangle and c is the hypotenuse\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"3%5E2%2B2%5E2=x%5E2\" Plug in a=3, b=2, and c=x. Now lets solve for x\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"9+%2B+4+=++x++%5E+2\" Square each individual term\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"1+3+=++x++%5E+2\" Combine like terms\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"s+q+r+t+%28+1+3+%29+=+s+q+r+t+%28++x++%5E+2+%29\" Take the square root of both sides\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Which approximates to...\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"3.60555127546399=x\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So our answer to the nearest hundredth is \r
\n" ); document.write( "\n" ); document.write( "\"x=3.61\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So the line segment is about 3.61 units long
