Angle of Depression

Section 4.8





You say?

 

yes

 

I promise to show my work for this and other precalculus questions but only on Friday, Saturday and Sunday moving forward.

 

Top of tower to ground level where cell phone user is standing 5 miles away is 120 + 800 = 920 feet.

Where did 800 feet come from?

Well, 1200 - height where cell phone user is standing.

I get 1200 - 400 = 800.

Let x = angle of depression.

tan x = 920/5

arctan[tan x ] = arctan(920/5)

x = 89.69°

Yes?
