A building that is 100 for tall casts a shadow that makes a 30 degree angle. Approximately how long in feet is the shadow across

skad [1K]

Answer: 173.20 ft

Step-by-step explanation:

Observe the attached image. To know how long the shadow is, we must find the length of the adjacent side in the triangle shown. Where the opposite side represents the height of the building

By definition, the function $tan (x)$ is defined as

$tan(x) = \frac{opposite}{adjacent}$

$opposite = 100\ feet\\x=30\°$

$adjacent = l$

Then

$tan(30\°) = \frac{100}{l}$

$l = \frac{100}{tan(30\°)}$

$l = 173.20\ ft$
