so we have three points, A, B and C, if indeed AC is the diameter of the circle, then half the distance of AC is its radius, and the midpoint of AC is the center of the circle, morever, since B is also on the circle, the distance from B to the center must be the same radius distance.
in short, half the distance of AC must be equals to the distance of B to the midpoint of AC, if indeed AC is the diameter.

now, let's check the distance from say A to the center, and check the distance of B to the center, if it's indeed the center, they'll be the same and thus AC its diameter.

Answer:
Hypotenuse legs
6 units arrowBoth 5 units, 1 unit
5 units arrowBoth 2 units, 3 units
8 units arrowBoth 5 units, 2 units
3 units arrowBoth 1 unit, 2 unit
Step-by-step explanation:
i got this because if u add
5+1= 6 units
2+3=5 units
5+2=8 units
1+2=3 units
You need to find out how many pints are in 2,4,6,8 quarts. by the way 1 quart equals 2 pints. so to start you off. 2 quarts would be 4 pints and so on
200 is the answer so it would equal to 2 hundreds
