Lying in the same straight line i think..
Answer:
Hint: 0 is x1, -2 is y1, 10 is x2, and -6 is y2.
Step-by-step explanation:
I'm not sure how to explain it, but that's how you can label your coordinates to make it easier to substitute it into the formula. The first number at the beginning of the coordinate is x and the other is y. For example, (3, 7). The three is x and the seven y. If you have two coordinates, then one group has a 1 underneath it while the other has a 2. Simply put, (x1, y1) and (x2, y2). The only thing left is to find the midpoint of segment AB (or line, not sure) by using the midpoint formula.

As of 7 being one side, subtract it with the whole...
When you subtract you get 10
Divide by 2 (or subtract 5)
So the two other sides of the triangle is 5m
A would equal 60 because you would divide 60 by 2 there for getting 30
hope this helps
