It will be -5 I pretty sure but I’m not sure
Answer:
D
Step-by-step explanation:
Remember that the sum of the interior angles of a triangle will always total 180.
Therefore:

Let’s solve for <em>x: </em>
Combine LIke Terms:

Add:

Subtract 80 from both sides:

Divide both sides by 25:

Therefore, the value of <em>x </em>is 4.
Now, to find A, we can substitute it for A.
A is measured by:

Substitute 4 for <em>x</em> and evaluate:

Hence, our answer is D.
16 can be expressed as a difference of two prime numbers in two ways, which
is:23 - 7 = 16, 19 - 3 = 16
Among the choices, 16 is expressed as (23 - 7), which is the difference of two prime numbers.
The only answer that makes sense to me is B.
