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 =
Given:
At a college, the tuition increased by 10%. Let b be the former cost of tuition.
Use the expression for the new cost of tuition.
To find:
The equivalent expression by combining like terms.
Solution:
We have,
On combining the like terms, we get
Therefore, the required equivalent expression is 1.10b.
