You can put this solution on YOUR website!
First, find the lengths of all the sides
\n" ); document.write( "(hypotenuse)2 = (side1)2 + (side2)2
\n" ); document.write( "\"5%2A2+=+3%2A2+%2B+x%2A2\"
\n" ); document.write( "\"x%2A2+=+5%2A2+-+3%2A2\"
\n" ); document.write( "\"x%2A2+=+25+-+9\"
\n" ); document.write( "\"x%2A2+=+16\"
\n" ); document.write( "\"x+=+4\"
\n" ); document.write( "It's what is known as a 3-4-5 triangle
\n" ); document.write( "The tangent function in trig is (opposite side) / (adjacent side)
\n" ); document.write( "For the angle opposite the length 3 side, call it A
\n" ); document.write( "Tan A = 3/4
\n" ); document.write( "For the angle opposite the length 4 side, call it B
\n" ); document.write( "Tan B = 4/3
\n" ); document.write( "The remaining angle, opposite the hypotenuse is 90 degrees, as
\n" ); document.write( "with any right triangle. Call it C
\n" ); document.write( "Tan C = Tan 90
\n" ); document.write( "Tan 90 = infinity. This is because the adjacent side is zero
\n" ); document.write( "and the reciprocal of zero is infinity. You need to plot it on
\n" ); document.write( "the unit circle to see this.
\n" ); document.write( "
\n" );
