Answer:
About 3000 feet
Step-by-step explanation:
This is a 30,60 90 triangle, all the angles in a triangle adds up to 180.
Use sin ratio
sin 60 = [tex]\frac{o}{4000}[/tex] o for opposite side of triangle from the 60 degree angle
o = 4000 (sin 60) = 3464.11
Use cosine
cos 30 = [tex]\frac{a}{3464.11}[/tex] a for adjacent side of triangle from the 30 degree angle
3464.11 (cos 30) = 3000.01
