From the given picture, we can see that 2 sides are congruen, then the given triangle is an isosceles triangle. In this triangle the base angles are congruent, so we can draw the following picture:

Now, since interior angles of any triangle add up to 180 degrees, we have

x+\frac{x}{2}+\frac{x}{2}=180

By combining similar terms, we get

\begin{gathered} \frac{4}{2}x=180 \\ 2x=180 \end{gathered}

Then, x is given as

\begin{gathered} x=\frac{180}{2} \\ x=90 \end{gathered}

Therefore, the answer is x=90 degrees

An observation from a normally distributed population is considered "unusual" if it is more than 2 standard deviations away from
Liula [17]

Answer:

Step-by-step explanation:

Given that an observation from a normally distributed population is considered "unusual" if it is more than 2 standard deviations away from the mean. There are several contaminants that can harm a city's water supply. Nitrate concentrations above 10 ppm (parts per million) are considered a health risk for infants less than six month of age.

We can say 1.59 and 2.52 if taken average would be the mean

Mean = 2.01

The deviations on either side = 2.52-2.01 = 0.41

This can be taken as 2 std dev

So std dev  = 0.205

Hence we can take nitrate concentration is normal with mean = 2.01 and std deviation is 0.205

N(2.01, 0.205)
