document.write( "tim needs to find the height of a tower surrounded by a fence, which prevents direct measurement of the tower's shadow length. Tim was instead able to find that the shadow was 650 feet longer at a 30 degree angle as compared to a 45 degree angle of the sun. Help Tim solve for the tower height.

Algebra.Com's Answer #366093 by mananth(16946)![]() ![]() You can put this solution on YOUR website! Let the shadow at 45 deg be x \n" ); document.write( "at 30 deg it is x+650 ft\r \n" ); document.write( "\n" ); document.write( "let height of tower be h ft\r \n" ); document.write( "\n" ); document.write( "Tan 45 = h/x\r \n" ); document.write( "\n" ); document.write( "but tan 45 = 1 \n" ); document.write( "so h = x\r \n" ); document.write( "\n" ); document.write( "Tan 30 = h/(h+650)\r \n" ); document.write( "\n" ); document.write( "1/sqrt(3)= h/(h+650)\r \n" ); document.write( "\n" ); document.write( "h+650 = h sqrt(3) \n" ); document.write( "hsqrt(3)-h = 650\r \n" ); document.write( "\n" ); document.write( "h(sqrt(3)-1)=650\r \n" ); document.write( "\n" ); document.write( "h= 650/(sqrt(3)-1)\r \n" ); document.write( "\n" ); document.write( "h= 888 ft \n" ); document.write( " |
