The correct answer is the third one.

Each x value (or domain) can only have one unique output. For example, if I had (2,7), then I could not have (2,14). If I had (3,15), then I could have (3,15) again, because they are the same point. If you need further explanation, just let me know. : )

kvasek [131]

Answer:

520 feets

Step-by-step explanation:

The height of the building, h can be obtuined using trigonometry ;

From the attached diagram, opposite side = 300 feets ; height, h = adjacent side

Hence,

Tan θ = opposite / Adjacent

Tan 30° = 300 / height

0.5773502 = 300 / height

Height = 300 / 0.5773502

Height = 519.615

Height = 520 feets
