10-5
Step-by-step explanation:
As per the attached figure, right angled has an inscribed circle whose center is .
We have joined the incenter to the vertices of the .
Sides MD and DL are equal because we are given that
Formula for area of a
As per the figure attached, we are given that side a = 10.
Using pythagoras theorem, we can easily calculate that side ML = 10
Points P,Q and R are at on the sides ML, MD and DL respectively so IQ, IR and IP are heights of MIL, MID and DIL.
Also,
So, radius of circle =
