D) The measures of the non- right angles in each triangle .
You plug 8 into where n is so it's 8-5
8-5= 3 so the answer is A
Answer:

Step-by-step explanation:
We are given the following in the question:
x: −4 −3 −2 −1 0
P(X=x): 0.2 0.3 0.1 0.2 0.2
We have to evaluate

Since it is a discrete probability distribution as

We can evaluate the probability as:

Thus, 0.4 is the require probability.
I would love to help, but what are the options?
Answer:
x = 104° because they are alternate interior angles and alternate interior angles are equal
