Hi;

Yes, it must some bit of roundoff error in calculation. I do not see any reason for it to be different based on reversing the triangle.

I have the result, but I do not yet know how to get it.

Row 1: Sqrt[175²+250²]-0.7-1/0.7 = 303.035318964, which is very close to 303. Maybe *so *close that Geogebra's rounding tipped the result to just under 303.

And could your program be contributing in some way too?

**New problem:**

**A cow is tied to one corner ( vertex ) of a 20 m square barn. The cow has a 50 m length of chain to keep it from escaping while it is grazing. How big is the cow's grazing area?**

**A says) Obviously a circle with a 50 m radius.**

**B says) Not quite, the barn interferes with that. It is closer to...**

**C says) I can not compute it even with a supercomputer.**

**D says) What is grazing?**

**E says) It is quite easy.**

**Can you answer the question?**

I have the result, but I do not yet know how to get it.

I'm not sure... The area of the overlapping chunk seems hard to get...

Hi;

That area can be tough and will take some work.

**New Problem:**

**ITCWY #200**

**a,b,c,d are positive and rational. The two chords are perpendicular. Neither chord is a radii. See the drawing below.**

**Can you find a general expression for the lengths of a,b,c,d? Or any expression showing what values would work?**

That is all I have since I am playing with a geogebra program. I do not have time to work on an analytical solution today.

I have the result, but I do not yet know how to get it.

It's not a long solution though...
