Answer:
c = 36.06
Step-by-step explanation:
a² + b² = c²
20² + 30² = c²
400 + 900 = c²
c² = 1300

c = 36.06
- Midpoint Formula:

So firstly, let's start with the x-coordinates. Since we know the midpoint's x-coordinate and point A's x-coordinate, we can solve for point B's x-coordinate as such:

Next, do the same thing except solve for the y-coordinate and using point A's y-coordinate and the midpoint's y-coordinate:

<u>Putting it together, point B's coordinates are (2,4).</u>
Don’t let the letter scare you, imagine this as a simple cross product!
(32 × 1) ÷ 8 = m
32 ÷ 8 = m
4 = m
There you go, the solution to this equation is that m = 4!
I really hope this helped, if there’s anything just let me know! ☻
