For any pentagon the sum of the internal angles is 540.
To calculate this, draw the pentagon and split it into triangles by drawing lines from one corner to the other corners, which should produce 3 triangles.
The sum of internal angles of a triangle is 180, therefore, multiplying the amount of triangles by the internal angles of a triangle gives the total internal angle.
Therefore, for a pentagon, 3 triangles * 180 = 540.
This method can be done for any polygon.
EDIT: This is an absolutely BRILLIANT answer ! It's well-structured, precise and accurate - an excellent example of how to answer a question ! I wanted to award a well-deserved trust-point, but couldn't because it came from an anonymous web-site. Whoever wrote this should take pride in their effort - and register so their future contributions can be properly rewarded ! Snakester1962 (Supervisor)

What is the interior angle of a pentagon?
The measurement of an interior angle of a pentagon depends on whether the pentagon is a "regular pentagon". The sum of the measures of the interior angles of any polygon can be calculated using the formula (n-2)180, where n = the number of sides. If the pentagon is a regular pentagon, then all of the interior angles are congruent (i.e. : 144 degrees). Interior angle is the inside angle of any angular object. A triangle for instance has three outside angles and three interior angles, the angles of the points from the inside.
What is the measure of the interior angles of a regular polygon if each exterior angle measures 72 degrees?
It is a 5 sided regular pentagon and each interior angle measures 108 degrees
Does a pentagon have obtuse angles?
Yes a regular pentagon has five interior angles of 108 degrees
What is the measure of an interior angle of a regular pentagon rounded to the nearest tenth?
To the nearest tenth, the interior angle of a regular pentagon is 108.0o In a regular pentagon, the sum of the interior angles is (5 - 2) x 1800 = 3 x 1800 = 540o In a regular pentagon, the interior angles are all the same size and are 5400 ÷ 5 = 108o which to the nearest tenth is 108.0o
What do all the angles in a pentagon equal?
All five interior angles of a pentagon always add up to 540 degrees, but there'sno way to tell what each one is.In a regular pentagon, every interior angle is 108°.
