incenter of a circle= Area/semi-perimeter

Area= \(\frac{1}{2}*6*8\)=24
Semi-perimeter= \(\frac{6+8+10}{2}\)=12

Incenter= 24/12=2

I don't think this formula is required on the GMAT. Is there any way to derive this solution for the given problem?

don't know if this is a common rule we need to know for the GMAT, but it is helpful in this 1 Case.

In a Right Triangle, the Inscribed Triangle's Radius (Inradius) is Equal to = (semi-perimeter) - Hypotenuse

x = (6 + 8 + 10) / 2 - 10
x = 12 - 10 = 2

Answer choice: B (if you know the obscure Rule, takes less than 30 seconds)
