Answer:

About 3000 feet

Explanation:

This is a 30,60 90 triangle, all the angles in a triangle adds up to 180.

Use sin ratio

sin 60 =
(o)/(4000) o for opposite side of triangle from the 60 degree angle

o = 4000 (sin 60) = 3464.11

Use cosine

cos 30 =
(a)/(3464.11) a for adjacent side of triangle from the 30 degree angle

3464.11 (cos 30) = 3000.01
