Step-by-step explanation:
Given:
To find :
Solution:
The sum of the measures of the interior angles of a polygon with 'n' sides is given as
Here we have n = 5 on substituting the values we get
Therefore,
m∠ U is 72°.
has critical points where
:
where is any integer. We get solutions in the interval
for
, for which
.
At this critical point, we have .
At the endpoints of the given interval, we have and
.
So we have the extreme values
