Answer to Problem 22PSC
The sum of the measures of the angles of the nonconvex polygon is
Explanation of Solution
Given information:
Nonconvex polygon as pentagon
The sum of the measures of the angles of the nonconvex polygon of ‘ n’ sides is given by
Here in the figure, n = 5
Therefore, The sum of the measures of the angles of the nonconvex polygon will be
b
To demonstrate: The sum of the measures of the angles of the nonconvex octagon is
b
Answer to Problem 22PSC
The sum of the measures of the angles of the nonconvex octagon is
Explanation of Solution
Given information:
Nonconvex polygon as Octagon
The sum of the measures of the angles of the nonconvex polygon is given by
Here, n = 8
Therefore, The sum of the measures of the angles of the nonconvex polygon =
c
To demonstrate: The sum of the measures of the angles of the nonconvex polygon of sides ‘ n’ is
c
Answer to Problem 22PSC
Yes, the sum of the measures of the angles of the nonconvex polygon is
Explanation of Solution
Given information:
The sum of the measures of the angles of the nonconvex polygon of ‘n’ sides is
Yes, the sum of the measures of the angles of the nonconvex polygon is given by
d
To demonstrate: The sum of the measures of the exterior angles of the nonconvex polygon of sides ‘ n’ is
d
Answer to Problem 22PSC
The sum of the measures of the exterior angles of the nonconvex polygon of sides ‘ n’ is
Explanation of Solution
Given information:
The sum of the measures of the exterior angles of the nonconvex polygon of sides ‘ n’ is
For any closed structure, formed by sides and vertex, the sum of the exterior angles is always equal to the sum of linear pairs and sum of interior angles. Therefore,
Hence, we got the sum of exterior angles of n vertex equal to 360 degrees.
