Sin is opposite over hypotenuse. Call the opposite side 6 and the hyp 10.

\n" ); document.write( "cos is adjacent over tangent. If you know Pythagorean triples you know the adjacent side has to be 8. Otherwise use the Pythagorean theorem: $\"a%5E2+%2B+b%5E2+=+c%5E2\"$ where a and b are the legs and c is hypotenuse.

\n" ); document.write( " $\"6%5E2+%2B+b%5E2+=+10%5E2\"$

\n" ); document.write( " $\"b%5E2+=+100+-+36+=+64\"$

\n" ); document.write( " $\"b+=+sqrt%2864%29+=+8\"$

\n" ); document.write( "tan = sin/cos = opp/adj = 6/8 = 3/4 = .75 \n" ); document.write( "
