Algebra.Com's Answer #41966 by josmiceli(19441)![]() ![]() You can put this solution on YOUR website! What is known? \n" ); document.write( "First, the post makes a right angle with the ground \n" ); document.write( "Then, if I were able to draw a straight line from the top of the post to \n" ); document.write( "some other point on the ground, I would have a right triangle \n" ); document.write( "The definition of the tangent of an angle is (opposite side) / (adjacent side) \n" ); document.write( "h = height of pole in meters \n" ); document.write( "so, tan 33.23 = h / 38 \n" ); document.write( "h = 38*tan 33.23 \n" ); document.write( "h = 38*.655 \n" ); document.write( "h = 24.895 m is height of pole \n" ); document.write( " |
