Juanita measures the angle of elevation from the ground to the top of an18-foot-tall tree as 30°. the image is of a tree whose height is 18 ft and its top is making an angle of 30 degrees with the ground. to the nearest tenth of a foot, how far is she from the tree?

Juanita is standing 31.17 ft far from the tree.

Step-by-step explanation:

Angle of elevation measured by Juanita =

Height of the tree = 18 ft

Also, an image of that tree whose height is 18 ft and its top is making an angle of 30°.This means length of the image is equal to the distance at which Juanita is standing.

In fig ΔABC

(tan 30° = 0.5773)

BC = 31.17 ft ≈ 31.2 ft

Juanita is standing 31.2 ft far from the tree.

answer: 80,000

step-by-step explanation:

the population doubles every day.

10,000*2=20,000 day 4

20,000*2=40,000 day 5

40,000*2=80,000 day 6
