A rope is dropped from the helicopter and it is perpendicular to the ground. What is the distance between Jeremiah and the rope?

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 =  o for opposite side of triangle from the 60 degree angle

o = 4000 (sin 60) = 3464.11

Use cosine

cos 30 =   a for adjacent side of triangle from the 30 degree angle

3464.11 (cos 30) = 3000.01

25/4

step-by-step explanation:

call segment cd's length x. because dc and ab are parallel, angle acd and cab, so triangles adc and abc are similar and we can set up the equation x / ac = ac / ab, or x / 5 = 5 / 4 and x = 25/4.

that is the sum

step-by-step explanation:

there are no other answers without knowing the variables values
