Assuming that a 370-foot tall giant redwood grows vertically, if I walk a certain distance from the tree and measure the angle of elevation to the top of the tree to be 58°, how far from the base of the tree am I?

Round your answer to four decimal places.

I am about _____ feet away from the base of the tree.

Use the Trig. function 'Tan(Tangent)

Tan(angle) = opposite (height) / adjacent(base)

Tan(58) = 370/base

Base = 370/Tan(58)

Base = 370/1.60033....

Base = 231.2 ft.

Let x ft be the distance, then

370/x=tan(58*)

=>

x=370/tan(58*)

=>

x=231.2016602~231.2017.

Ans. you are about 231.2017 ft from the base of the tree.

If we would treat the height of the redwood tree perpendicular from the horizontal,

we can solve for the distance from the base

using trigonometric ratios of a right triangle.

Since we know that

tan (θ) = opposite / adjacent,

then tan (58°) = 370/x

x = 370/tan (58°)

x = 231.20166020645112

Therefore, you are approximately

231.2017 ft away from the base of the tree.

You have the opposite and want adjacent, so use Tan

Tan 58 = Height/distance

Distance = height/tan 58 = 370/tan 58

About 230 feet, you should do the actual calc...
