Question

From the top of a building, 40 feet above the ground, a construction worker locates a rock at a 12° angle of depression. How far is the rock from the building? ​

Answer 1

Answer:

188 m

Step-by-step explanation:

$\tan(12) = \frac{40}{x} \\ x = \frac{40}{ \tan(12) } \\ x = 188$

Answer 2

Answer:

I think that the other answer is WRONG

tan(12) = $\frac{x}{40}$

x = tan(12)*40 = 8.5

Step-by-step explanation:

$\frac{sin\left(78\right)}{40}=\frac{sin\left(12\right)}{x}$ = 8.5
