You can put this solution on YOUR website!
If two angles are complementary, the sum of their measures is 90 degrees.
\n" ); document.write( ".
\n" ); document.write( "Call one of the angles x.
\n" ); document.write( ".
\n" ); document.write( "This means that its complement is 90 - x degrees.
\n" ); document.write( ".
\n" ); document.write( "But the difference in their measures is 12 degrees. Therefore, you can write the equation:
\n" ); document.write( ".
\n" ); document.write( "x - (90 - x) = 12
\n" ); document.write( ".
\n" ); document.write( "Since the parentheses are preceded by a minus sign, you can remove the parentheses if you also
\n" ); document.write( "change the signs of the terms inside the parentheses. Therefore, when you remove the parentheses
\n" ); document.write( "the equation becomes:
\n" ); document.write( ".
\n" ); document.write( "x - 90 + x = 12
\n" ); document.write( ".
\n" ); document.write( "Combine the two x terms on the left side to get:
\n" ); document.write( ".
\n" ); document.write( "2x - 90 = 12
\n" ); document.write( ".
\n" ); document.write( "Get rid of the -90 on the left side by adding 90 to both sides to get:
\n" ); document.write( ".
\n" ); document.write( "2x = 102
\n" ); document.write( ".
\n" ); document.write( "Solve for x by dividing both sides of the equation by 2 to get:
\n" ); document.write( ".
\n" ); document.write( "x = 102/2 = 51
\n" ); document.write( ".
\n" ); document.write( "So the measure of one of the two angles is 51 degrees. Its complement is the amount that
\n" ); document.write( "must be added to that angle such that this sum is 90 degrees. By subtracting 51 from 90
\n" ); document.write( "degrees, you find that the complement of the angle is an angle of 39 degrees. Note that
\n" ); document.write( "the difference in the two angles is 51 - 39 = 12 degrees, just as the problem specified.
\n" ); document.write( ".
\n" ); document.write( "The answer to this problem is that the measures of the two complementary angles are 51
\n" ); document.write( "degrees and 39 degrees.
\n" ); document.write( ".
\n" ); document.write( "Hope this helps you to understand the problem a little better.
