Algebra.Com's Answer #727625 by Alan3354(69443)![]() ![]() You can put this solution on YOUR website! Pam sees a hot-air balloon at an altitude of 520m with an angle of elevation of 42°24'. Four minutes later, it has drifted in a straight line towards Pam, at the same altitude, so that it then has an angle of elevation of 67°10'.\r \n" ); document.write( "\n" ); document.write( "a) How far had it drifted? \n" ); document.write( "--- \n" ); document.write( "It's a right triangle. The tangent of the angle = y/x = height/distance. \n" ); document.write( "Find the 2 distances, subract. \n" ); document.write( "================== \n" ); document.write( "b)At what speed was the hot-air balloon travelling? \n" ); document.write( "To find meters/minute, divide the meters by the minutes. \n" ); document.write( " \n" ); document.write( " |
