Step-by-step explanation:
Formula:

= 3
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.
Answer:
10
Step-by-step explanation:
d = √(x2 -x1)² + (y2 - y1)²
√(-6 - 0)² + [1 - (-7)]²
√(-6)² + (8)²
√(36) + (64)
√100
= 10
