To answer this question, you’ll use your knowledge that the sum of the interior angles of any pentagon is always 540 degrees. All you have to do is to subtract your four known angles from the total of 540 degrees. Doing this, you find your answer to be this: 540 – 135 – 78 – 119 – 117 = 91 degrees.

What is the sum of all the angles of a pentagon?

So if we know that a pentagon adds up to 540 degrees, we can figure out how many degrees any sided polygon adds up to. Hexagon has 6, so we take A heptagon has 7 sides, so we take the hexagon’s sum of interior angles and add 180 to it getting us, degrees.

What is the sum of the interior angles of a pentagon 5 sides )?

The General Rule

ANSWER: 19. SOLUTION: The sum of the interior angle measures is or 540.

What is the sum of the interior angles of a 13 Gon?

Question 130236: What is the sum of the measures of the interior anles of a convex 13-gon? There is a formula… the sum of the measures of the interior angles of a convex n-gon is (n-2)180 degrees. For a triangle, n=3, so it’s (1)180=180 degrees.

What is the sum interior angles of a 100 gon?

In geometry, a hectogon or hecatontagon or 100-gon is a hundred-sided polygon. The sum of all hectogon’s interior angles are 17640 degrees.

What is the sum of the interior angles of the 1616 sided polygon?

So the sum of all of the measures of the interior angles of a 16-sided polygon is 2520 degrees.
