Answer:

x = 8°

Step-by-step explanation:

Because this triangle is an equilateral triangle, as indicated by the lines which say all lines are congruent, it means every angle, R S and T, are exactly the same amount. 60°

This means that angle S = 60 so:

7x +4 = 60

Simply move the 4 over to the other side, making it a negative:

7x = 60 - 4

7x = 56

So now simply divide both sides by 7:

$\frac{7x}{7} = \frac{56}{7}$

x = 8

<h3>So the value of x is 8°!</h3>
<h2>Hope this helps!</h2>

What can you tell about the mean of each distribution

Llana [10]

Step-by-step explanation:

In the case of a discrete probability distribution of a random variable X, the mean is equal to the sum over every possible value weighted by the probability of that value; that is, it is computed by taking the product of each possible value x of X and its probability p(x), and then adding all these products together
