Please help me solve this problem: one angle of a linear pair is 10 more than two-thirds the other angle. Find both angles. \n" ); document.write( ". \n" ); document.write( "If two angles are a \"linear pair\", the sum must be 180 degrees. \n" ); document.write( ". \n" ); document.write( "Let x = one angle \n" ); document.write( "rhen \n" ); document.write( "180-x = second angle \n" ); document.write( ". \n" ); document.write( "Our equation is derived from: \"one angle of a linear pair is 10 more than two-thirds the other angle\": \n" ); document.write( "x = (2/3)(180-x) + 10 \n" ); document.write( "multiplying both sides by 3: \n" ); document.write( "3x = (2)(180-x) + 30 \n" ); document.write( "3x = 360-2x + 30 \n" ); document.write( "5x = 360 + 30 \n" ); document.write( "5x = 390 \n" ); document.write( "x = 78 degrees \n" ); document.write( ". \n" ); document.write( "second angle: \n" ); document.write( "180-x = 180-78 = 102 degrees \n" ); document.write( ". \n" ); document.write( "Answer: 78 and 102 degrees\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
