Algebra.Com's Answer #331282 by ankor@dixie-net.com(22740) You can put this solution on YOUR website! The measure of two complementary angles are 16z-9 and 4z+3. \n" ); document.write( "Find the measures of the angles. \n" ); document.write( ": \n" ); document.write( "Two complementary angles add up to 90, so you have a simple equation \n" ); document.write( "(16z-9) + (4z+3) = 90 \n" ); document.write( "Remove brackets, combine like terms \n" ); document.write( "16a + 4z - 9 + 3 = 90 \n" ); document.write( "20z - 6 = 90 \n" ); document.write( "20z = 90 + 6 \n" ); document.write( "z = \n" ); document.write( "z = 4.8 \n" ); document.write( ": \n" ); document.write( "Find the angles using 4.8 for z \n" ); document.write( "Angle 1: \n" ); document.write( "16(4.8) - 9 = \n" ); document.write( "76.8 - 9 = 67.8 degrees \n" ); document.write( "Angle 2: \n" ); document.write( "4(4.8) + 3 = \n" ); document.write( "19.2 + 3 = 22.2 degrees \n" ); document.write( ": \n" ); document.write( "Check that 67.8 + 22.2 = 90, as it should \n" ); document.write( ": \n" ); document.write( "Was this explained well enough for you? \n" ); document.write( " \n" ); document.write( " |
