1)  The triangle is a right-angle triangle, therefore:

 

Cos(60) = The distance to helicopter / distance between her and Jeremiah

1/2         = D / 4,000

D = 4,000 x 1/2

D = 2,000 ft. distance between Amanda and the helicopter.

 

2)

Cos(30) = Distance from Jeremiah to helicopter / 4,000

0.866     = D / 4,000

D =0.866 x 4,000

D =~ 3,464 ft -distance between Jeremiah and the helicopter.
