How tall is the lamp post? (In a 30-60-90 right triangle, the side opposite 30 is one-half the length of the hypotenuse.) \n" ); document.write( "
Algebra.Com's Answer #26539 by fractalier(6550)![]() ![]() You can put this solution on YOUR website! If you make a proper diagram, you discover that the 8 foot shadow is opposite the 30 degree angle...that means the hypotenuse is 16 feet and the height of the flagpole is 8*sqrt(3) feet tall... \n" ); document.write( " |
