Answer
where is the pdf?
Step-by-step explanation:
Ten, but you have to do it to both sides.
Answer:
answer = 100 X100 - 25 X 25 = x
10000 - 625 = x
Answer: 6.92 m
Step-by-step explanation:
Assuming the image is the attached below, we have a right triangle, where one of the legs is the 4 m high pole and the other leg the shadow.
Now, the tangent function is defined as:
![tan \theta=\frac{Opposite-leg}{Adjacent-leg}](https://tex.z-dn.net/?f=tan%20%5Ctheta%3D%5Cfrac%7BOpposite-leg%7D%7BAdjacent-leg%7D)
Since the Sun is at an angle
and the adjacent leg is the shadow
we have:
![tan(30\°)=\frac{4 m}{s}](https://tex.z-dn.net/?f=tan%2830%5C%C2%B0%29%3D%5Cfrac%7B4%20m%7D%7Bs%7D)
Isolating
:
![s=\frac{4 m}{tan(30\°)}](https://tex.z-dn.net/?f=s%3D%5Cfrac%7B4%20m%7D%7Btan%2830%5C%C2%B0%29%7D)
This is the length of the shadow
To find the area you have to have a formula,
A= S²
A=3 2/5× 3 2/5
A=289/25
A=11 14/25
