Question

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.

Answer 1

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. 

Answer 2

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.

Answer 3

 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?

 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.

Answer 4

SOHCAHTOA

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...
