To find the angle of the helicopter, we are going to take advantage of the fact the the sum of the interior angles of a triangle is always 180°. Lets denote that angle with 
, so:
Look what we have here: a angle of 90°, so our triangle is a right triangle.
Now, let
be the distance between Amanda and the helicopter. Using the law of sines:
Remember that sine of 90 ° is equal to 1, so:
We can conclude that the distance between Amanda and the helicopter is 2000 feet.
