You can put this solution on YOUR website!
i believe you are dealing with an isosceles triangle.
\n" ); document.write( "5 * 16 = 80 miles.
\n" ); document.write( "the ship is going 80 miles in one direction when it should be going 80 miles in the other direction.
\n" ); document.write( "the difference between the two directions is 2.6 degrees.
\n" ); document.write( "that's an isosceles triangle with two legs of 80 miles each and a vertex of 2.6 degrees.
\n" ); document.write( "the distance between the two points is the base of the isosceles triangle.
\n" ); document.write( "drop a perpendicular and that divides the base into 2 equal parts.
\n" ); document.write( "2 right triangles are formed, each with an angle of 1.3 degrees opposite its base.
\n" ); document.write( "sin(1.3) = opposite / hypotenuse = x / 80
\n" ); document.write( "x is the opposite.
\n" ); document.write( "80 is the hypotenuse.
\n" ); document.write( "sin(1.3) = x/80
\n" ); document.write( "solve for x to get x = 80 * sin(1.3) which makes x equal to 1.814986686 miles.
\n" ); document.write( "that's half the distance between the two points.
\n" ); document.write( "the distance between the two points will be 3.629973372 miles.
\n" ); document.write( "that's how far away the ship will be from its intended destination.\r
