Algebra.Com's Answer #241297 by ankor@dixie-net.com(22740)![]() ![]() You can put this solution on YOUR website! My explanation: \n" ); document.write( "Complementary angles are angles that add up to 90. \n" ); document.write( "For example, 55 degrees and 35 degrees are complementary, they add up to 90 \n" ); document.write( "If you were asked,\"What is the complement of 25 degrees?\" you would \n" ); document.write( "say 90 - 25 = 65 degrees and is the complement of 25 \n" ); document.write( "; \n" ); document.write( "The sum of the measures of two complementary angles is 90 degrees. (we just said that) \n" ); document.write( "Call the two angles, x & y, they are complementary therefore: \n" ); document.write( "x + y = 90 \n" ); document.write( ": \n" ); document.write( "Find the measures of two complementary angles whose measures are in the ratio of 1:4. \n" ); document.write( "Therefore: \n" ); document.write( " \n" ); document.write( "Cross multiply \n" ); document.write( "y = 4x \n" ); document.write( ": \n" ); document.write( "return to the equation x + y 90 \n" ); document.write( "Replace y with 4x, \n" ); document.write( "x + 4x = 90 \n" ); document.write( "5x = 90 \n" ); document.write( "x = \n" ); document.write( "x = 18 degees \n" ); document.write( "We know y = 4x, therefore \n" ); document.write( "y = (4*18) \n" ); document.write( "y = 72 degrees \n" ); document.write( ": \n" ); document.write( "These two angle add up to 90 and have the ratio of 1:4 \n" ); document.write( "; \n" ); document.write( "Did this shed some light on complementary angles?? \n" ); document.write( " |
