Algebra.Com's Answer #621912 by Alan3354(69443)![]() ![]() You can put this solution on YOUR website! A ship is due west of a lighthouse. A second ship is 12 miles south of the first ship. The bearing from the second ship to the lighthouse is N64˚E.\r \n" ); document.write( "\n" ); document.write( "How far, to the nearest tenth of a mile, is the second ship from the lighthouse? \n" ); document.write( "------------------ \n" ); document.write( "This is a right triangle. \n" ); document.write( "The distance from ship 2 to the lighthouse is the hypotenuse. \n" ); document.write( "The interior angle at the 2nd ship is 64 degs. \n" ); document.write( "--> cos(64) = 12/hyp \n" ); document.write( "hyp = 12/cos(64) \n" ); document.write( "=~ 27.4 miles \n" ); document.write( " |
