Andrew wants to measure the height of a traffic light. He walks exactly 20 feet from the base of the traffic light and looks up.

slava [35]

Answer-

The height of the traffic light is 21.8 feet.

Solution-

As shown in figure, we can see the right triangle formed from the situation,

From the question,

BC = the distance walked by Andrew from the traffic light = 20 feet

Height of Andrew's eye = 5 feet

Height of the traffic light = AB + Height of Andrew's eye

From the properties of triangle,

$\Rightarrow \tan \theta =\frac{Height}{Base}$

$\Rightarrow \tan C =\frac{AB}{BC}$

$\Rightarrow AB=\tan C\times BC$

$\Rightarrow AB=\tan 40\times 20$

$\Rightarrow AB=16.8$

Therefore, height of the traffic light = AB + Height of Andrew's eye = 16.8+5 = 21.8 feet
