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: y = -12x + 108

step-by-step explanation: do (y = m x+b) formula.

after simplifying it i got: -36.25 as my answer. hope that !
