Answer:
0.40 foot
Step-by-step explanation:
In the first case, a 50 - foot building casts a- foot shadow (1-foot). Let the angle of elevation of the sun from the shadow be represented by θ.
Then:
Tan θ =
Tan θ =
Tan θ = 50
⇒ θ = 50
= 88.8542
=
The angle of elevation is approximately .
For a 20-foot pole,
Tan θ =
Tan =
x =
= 0.4015
= 0.40 foot
The length of the shadow of the pole is 0.40 foot.
