Answer:
x = 22.93 feet
Step-by-step explanation:
Given that,
The sun is 70° above the horizon.
We need to find the length of the shadow cast by a building 63ft tall.
Let the length of the shadow be x. We can find it using trigonometry as follows :
[tex]\tan\theta=\dfrac{P}{B}\\\\\tan(70)=\dfrac{63}{x}\\\\x=\dfrac{63}{\tan(70)}\\\\x=22.93\ ft[/tex]
So, the length of the casted shadow is equal to 22.93 feet.
