Answer:
θ = ![30^{0}](https://tex.z-dn.net/?f=30%5E%7B0%7D)
Step-by-step explanation:
Since the vertical height of the mountain is 800 feet, and the distance from the top to its base is 1600 feet. Let the angle of elevation be represented by θ, applying the required trigonometric function;
Sin θ = ![\frac{opposite}{hypotenuse}](https://tex.z-dn.net/?f=%5Cfrac%7Bopposite%7D%7Bhypotenuse%7D)
Sin θ = ![\frac{800}{1600}](https://tex.z-dn.net/?f=%5Cfrac%7B800%7D%7B1600%7D)
= 0.5
θ =
0.5
θ = ![30^{0}](https://tex.z-dn.net/?f=30%5E%7B0%7D)
Thus, the angle of elevation from the base to the top of the mountain is
.

hey friend it is Observational study because it says that her records hourly temperature over the course of several years in order to make a decision(variations) or to analyse his experiments. ;)
Answer:
Rational
Step-by-step explanation:
1.256 is not a whole #, and it's also not an integer. An integer is basically whole #s and their opposites. The # is not irrational. 1.256 is a terminating decimal, and can be turned into a fraction. 1.256 = 1 32/125.
