The shadow of a 60 foot pole is a 100 feet long. What is the angle of evaluation from the end of the shadow to the top of the po
Lilit [14]

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}

So, the angle of elevation is 36.86 degrees.

An operation that is done to a value and it stays the same, it is called the "identity property".

Some quick examples:

Adding any number with zero will result in the same number.

Multiplying any number with one will result in the same number.

Hope this helps!

Mashcka [7]

Answer:

The variance of the given data is 106.9667

Step-by-step explanation:

The variance, S² of a sample is given by the expression;

S^2 = \dfrac{\sum \left (x_{i}-\bar{x}  \right )^{2}}{n-1}

Where:

x_{i} = One of the observations

\bar{x} = The mean of the observations

n = Number in the sample = 6

The mean = Σx_{i}/n = (26  + 32 + 29  + 16  + 45  + 19 )/6 = 167/6 = 27.833

Therefore, we have;

S² = ((26 - 27.833)²+(32 - 27.833)²+(29 - 27.833)²+(16 - 27.833)²+(45 - 27.833)²+(19 - 27.833)²)/(6 - 1) = 106.9667.
