Use common core and guess, you’ll still get it right for trying

I'm a geometry teacher so I'll help you out.
If the hypotenuse is OC then CA and AO must be perpendicular to each other to make that right angle.
Since we don't know what the exact point for O is we can get the slope of CA using the slope formula (y2-y1)/(x2-x1). Plugging in numbers we get (1--4)/(10-3) which = 5/7 for the slope of CA.
The perpendicular slope has to be the opposite +- sight and the reciprocal, so -7/5.
Now I can plug AO into the slope formula and set it equal to -7/5. With numbers plugged in it looks like (3--4)/(d-3)=-7/5. Simplified it would be 7/(d-3)=-7/5. Cross multiply to get -7(d-3)=35.
Distribute: -7d+21=35.
Subtract 21 from both sides: -7d=14.
Divide: d=-2

First, you need to translate that problem to English..

First, mark your coordinates. C10 & C1, A3 & A-4, Od & O3.
I don't have anything in front of me to chart it out, but I think the formula is something like the square root of x^2 + y^2/square root of x^2 + y^2 1/2x^2
Its been awhile since I did geometry. I could be completely wrong.

All you need to know is:
A2 + B2 = C2
A2 + B2 = C2

The limit doesn't exist

-2.
A->O and A->C need to be perpendicular, so their dot product needs to be zero.
(3-d) × (3-10) + (-4-3) × (-4-1) = 0
-21 + 7×d + (-7 × -5) = 0
-21 +35 + 7×d = 0
14 + 7×d =0
d = -2

Are you trying to put the D in AOC?

Common Core or regular?

What does common poultry need geometry for?
