Let's recall what complementary angles really are:
\n" ); document.write( "Two angles are complement if they sum to 90 degrees. \r
\n" ); document.write( "\n" ); document.write( "Okay, so for the first question we will let x be the angle so the other angle must be x-60. Since they are each others complement we know:
\n" ); document.write( "\"%28x-60%29%2Bx=90\"
\n" ); document.write( "\"2x-60=90\"
\n" ); document.write( "\"2x-60%2B60=90%2B60\"
\n" ); document.write( "\"2x=150\"
\n" ); document.write( "\"2x%2F2=150%2F2\"
\n" ); document.write( "\"x=75\"
\n" ); document.write( "So the two angles are 75 and 75-60=15.
\n" ); document.write( "This means that the ratio between the two is 75:15 which can be reduced to 5:1. \r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "For the second question, it is very similar...
\n" ); document.write( "Let y be the angle so then the other angle is y-30.
\n" ); document.write( "\"y%2B%28y-30%29=90\"
\n" ); document.write( "\"2y-30=90\"
\n" ); document.write( "\"2y=120\"
\n" ); document.write( "\"y=60\"
\n" ); document.write( "So the two angles are 60 and 60-30=30.
\n" ); document.write( "This means that the ratio of the smaller to the larger angle is 30:60 which can be reduced to 1:2.
\n" ); document.write( "
\n" );
