A which is 29 degrees, \n" ); document.write( "side CA of 18 meters, \n" ); document.write( "and a right angle which is angle C. \n" ); document.write( "--------------------------------------- \r \n" ); document.write( "\n" ); document.write( "Here's what I found out so far: \n" ); document.write( "that angle b = 61 degrees \n" ); document.write( "but I do not know how to figure out CB and BA \n" ); document.write( "-------------------- \n" ); document.write( "Draw the picture. \n" ); document.write( "CB is opposite angle A=29 degrees. \n" ); document.write( "BA is opposite angle C so BA is the hypotenuse \n" ); document.write( "CA is opposite angle B \n" ); document.write( "---------------------- \n" ); document.write( "So, cos(A) = adjacent/hypotenuse \n" ); document.write( "cos(29) = 18/hypotenuse \n" ); document.write( "hypotenuse = 18/cos(29) = 20.58 \n" ); document.write( "----------------------------------- \n" ); document.write( "sin(A) = CB/hypotenuse \n" ); document.write( "CB = hypotenuse*sin(A) \n" ); document.write( "CB = 20.58*0.4848.. \n" ); document.write( "CB = 9.97738.... \n" ); document.write( "========================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
