A plane rises from​ take-off and flies at an angle of 17 degrees with the horizontal runway. 
When it has gained 800 ​feet, find the distance the plane has flown.
~~~~~~~~~~~~~~~~~


<pre>
Let d be the distance. Then


    sin(17°) = {{{800/d}}};


    d = {{{800/sin(17^o)}}} = {{{800/0.2924}}} = 2736 ft   (rounded).    <U>ANSWER</U>
