Answer:
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 <em>area</em> of a
As per the figure attached, we are given that side <em>a = 10.</em>
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 =
