The definition of complementary angles is two acute angles that add up to 90 degrees. Written as a formula:\r
\n" ); document.write( "\n" ); document.write( "A+B = 90 (A= measure of angle A, B=measure of angle B, A and B are complementary)\r
\n" ); document.write( "\n" ); document.write( "We also know that angle A is 38 degrees less than B. So you can also write this as a formula:
\n" ); document.write( "A = B-38\r
\n" ); document.write( "\n" ); document.write( "Now we can combine these formulas by plugging formula two into formula one for A and solving for B:
\n" ); document.write( "A+B = 90
\n" ); document.write( "(B-38) + B = 90
\n" ); document.write( "2B - 38 = 90
\n" ); document.write( "2B = 128
\n" ); document.write( "B = 64
\n" ); document.write( "So the measure of angle B is 64 degrees. Now plug this into formula two to find A:
\n" ); document.write( "A = B-38
\n" ); document.write( "A = 64-38
\n" ); document.write( "A = 26\r
\n" ); document.write( "\n" ); document.write( "The measure of angle A is 26 degrees.
\n" ); document.write( "
\n" );
