u divide in triangls and add them all up
A pentagon has an obtuse angle
the angle sum of a pentagon is 540.
a pentagon.
72 degrees
to find the entire angle sum of a pentagon you would have to subtract 2 from 5, because 5 is the number of sides. You then take 3 and multiply it by 180. if it is a regular pentagon you just simply divide 540 by 5 (the number of angles) and that is the measure of each angle in the pentagon. If it isn't a regular pentagon you subtract the 3 angle measures you know from 540 and then with the remaining number you use thereoms and postulates and stuff to find the angle measures
An angle in a pentagon can have any value between 0 and 360 degrees.
Answer72 degrees to find the exterior angle of a polygon just divide 360 by the number of sides. so for a pentagon it would be:360 divided by 5 which is 72 degrees
5th angle of the pentagon: 540-93-87-97-153 = 110 degrees
The measure of one angle of a regular pentagon is 108 degrees.
obtuse angle
Usually, the measure of an exterior angle of a pentagon is greater.
a pentagon's inside angle is 540 degrees
