Question

True or false the angle

Answer 1

Answer:

Second option: False

Step-by-step explanation:

You need to use the following identity:

$sin\alpha=\frac{opposite}{hypotenuse}$

Let be "x" the lenght of the buildings's shadow.

$opposite=x$ (Lenght of building's shadow)

You can observe in the figure that:

$\alpha=75\°\\\\hypotenuse=50ft$

Substitute these values into  $sin\alpha=\frac{opposite}{hypotenuse}$ and solve for ""x":

$sin(75\°)=\frac{x}{50}\\\\(50)(sin(75\°))=x\\\\x=48.29\°$

Therefore, the length of its shadow IS NOT 12.94 feet.
