Let x = measure of ∠A\r \n" ); document.write( "\n" ); document.write( "Given that, \n" ); document.write( "∠A = 3∠B + 25° and \n" ); document.write( "∠A + ∠B = 165°\r \n" ); document.write( "\n" ); document.write( "x = 3∠B + 25° \n" ); document.write( "x + ∠B = 165°\r \n" ); document.write( "\n" ); document.write( "Substituting, \n" ); document.write( "(3∠B+25°)+∠B = 165° \n" ); document.write( "4∠B+25° = 165° \n" ); document.write( "4∠B = 165°-25° \n" ); document.write( "4∠B = 140° \n" ); document.write( "∠B = 35°\r \n" ); document.write( "\n" ); document.write( "∠A + ∠B = 165° \n" ); document.write( "∠A + 35° = 165° \n" ); document.write( "∠A = 165°-35° \n" ); document.write( "∠A =130° \n" ); document.write( " |
