A point lies inside an equilateral triangle with sides of length s. Its distances from the 3 sides are x, y, and z. What can you say about x+y+z? Prove your answer.

I know how to build a diagram for this but I am stuck after that? Any ideas?

Is it true that the area of the whole triangle is $\displaystyle \displaystyle \frac{xs}{2}+\frac{ys}{2}+\frac{zs}{2}?$

Yes if we are using an equilateral triangle then this must be true.
