Algebra.Com's Answer #730808 by josgarithmetic(39620)![]() ![]() ![]() You can put this solution on YOUR website! The string length from person's hand to the kite is the hypotenuse of a right triangle. How high the kite is one of the legs, the leg wanted. Angle opposite this leg is given. \r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "If y is the height of the kite then \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "----------------------------------------------------------------- \n" ); document.write( " the string is taut and held 1 m above the ground, \n" ); document.write( "-----------------------------------------------------------------\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "That part means, you are looking for y+1. \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "--- \n" ); document.write( "answer as a number of metres (not in scientific notation) and to two significant figures. \n" ); document.write( "---\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "If you calculator shows you 12.1530034928386 with maybe further digits after that, but you want TWO SIGNIFICANT FIGURES, then you want \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "If the instructions said, \"to the nearest hundredth\" then you would report |
