A triangle has corners at #(2 , 9 )#, #(3 ,7 )#, and #(1 ,1 )#. What is the radius of the triangle's inscribed circle?
1 Answer
Explanation:
From the given data:
Let A(2, 9) and B(3,7) and C(1,1)
We let side a the distance B to C
We let side b the distance A to C
We let side c the distance A to B
Compute the lengths of the sides
We are now ready to compute for the radius
Formula
God bless....I hope the explanation is useful.
