Answer:
θ = 36.86°
Step-by-step explanation:
Given that,
The shadow of a 60 foot pole is a 100 feet long.
We need to find the angle of elevation from the end of the shadow to the top of the pole.
Height, h = 60 foot
Hypotenuse, H = 100 feet
Using trigonometry to find it.
![\sin\theta=\dfrac{\text{Height}}{\text{Hypotenuse}}\\\\\sin\theta=\dfrac{60}{100}\\\\\theta=\sin^{-1}(\dfrac{60}{100})\\\\\theta=36.86^{\circ}](https://tex.z-dn.net/?f=%5Csin%5Ctheta%3D%5Cdfrac%7B%5Ctext%7BHeight%7D%7D%7B%5Ctext%7BHypotenuse%7D%7D%5C%5C%5C%5C%5Csin%5Ctheta%3D%5Cdfrac%7B60%7D%7B100%7D%5C%5C%5C%5C%5Ctheta%3D%5Csin%5E%7B-1%7D%28%5Cdfrac%7B60%7D%7B100%7D%29%5C%5C%5C%5C%5Ctheta%3D36.86%5E%7B%5Ccirc%7D)
So, the angle of elevation is 36.86 degrees.
Rounded to the nearest tenth, the square root of 149 is 12.2.

True… irrational numbers focus more around square roots that cant be simplified into a single number, or symbols like pi. while not all rational numbers are whole, an irrational number can never be whole.
