Algebra.Com's Answer #332651 by chessace(471)![]() ![]() You can put this solution on YOUR website! Slope of a line = tan (its angle) and = coefficient of x in normal form. \n" ); document.write( "So angle(line) = arctan(coefficient of x) \n" ); document.write( "Ans = angle (5x+8) - angle (x+4) \n" ); document.write( "= arctan(5) - arctan(1) \n" ); document.write( "= 78.7 - 45 \n" ); document.write( "= 33.7 degrees \n" ); document.write( " \n" ); document.write( " |
