Question

What is the line of sight distance from the television camera to the base of the stadium?

Answer 1

Given the following information

television camara at 13°

altitude = 400

since the formed angle is a 90° angle then

90-13= 77

The trigonometric function that relates Hyp angle and Adj is Cos

then

`Cos(\theta)=(Adj)/(Hyp)`

where

angle = 77

adj=400

Hyp= distance from camara to thestadium =?

then

`Cos(77)=(400)/(Hyp)`
`Hyp=(400)/(Cos(77))`
`Hyp=(400)/(Cos(77))`
`Hyp=(400)/(0.22495)`
`Hyp=1778.1645`

Round to the nearest meter

the line of the sight is approximately

1778 m
