Algebra.Com's Answer #297614 by ankor@dixie-net.com(22740) You can put this solution on YOUR website! two masts are 20 m and 12 m high.if the line joining their tops make an angle of 35 degree with the horizontal; \n" ); document.write( " find their distance apart. \n" ); document.write( ": \n" ); document.write( "Draw this out, you can see a right triangle is is formed by the horizontal line between the poles, the line drawn between the tops of the poles (hypotenuse) and a side of 8', the difference in the height of the poles. \n" ); document.write( ": \n" ); document.write( "Find the interior angle formed by the line joining the tops \n" ); document.write( "90 - 35 = 55 degrees \n" ); document.write( ": \n" ); document.write( "Use the tangent which is the side opposite/side adjacent. \n" ); document.write( ": \n" ); document.write( "Side adjacent = 8', find side opposite (d) (horizontal dist between the poles) \n" ); document.write( "tan(55) = \n" ); document.write( "1.428 = \n" ); document.write( "d = 1.428 * 8 \n" ); document.write( "d = 11.425 ft between the poles \n" ); document.write( " |
