#1**+2 **

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.
