9/25 * 90 = 32.4 deg for left part of angle c
\n" ); document.write( "90-32.4=57.6 deg right part of angle c
\n" ); document.write( "angle a=57.6
\n" ); document.write( "angle b=32.4
\n" ); document.write( ".
\n" ); document.write( "sin(32.4)=9/hyp
\n" ); document.write( ".5358=9/h
\n" ); document.write( "h=9/.5358=16.8 AC
\n" ); document.write( "16.8/3=5.6 AE
\n" ); document.write( "5.6*2=11.2 CE
\n" ); document.write( ".
\n" ); document.write( "9^2+a^2=16.8^2
\n" ); document.write( "81a^2=282.24
\n" ); document.write( "a^2=201.24
\n" ); document.write( "a=CD=14.2
\n" ); document.write( ".
\n" ); document.write( "14.2^2+16^2=BC^2
\n" ); document.write( "=483.88
\n" ); document.write( "BC=22.0
\n" ); document.write( ".
\n" ); document.write( "I'll let you find CF and EF
\n" ); document.write( "Let me know if you have trouble.
