## What is the sum of the interior angles of the polygon with 15 sides?

A pentadecagon is a polygon with 15 sides, and the sum of its interior angles is 2340 degrees.

What is the sum of the measures of the interior angles of a 15 sided polygon apex?

All interior angles add up to (n-2)180 degrees. Therefore all the interior angles of your 15 sided regular polygon add up to 15-2 = 13180 degrees = 2340 degrees.

How much is each angle of a 15 sided regular polygon How much is each outer angle?

Exterior angle=24 for polygon of 15 sides.

### Does a Heptagon have 7 sides?

In geometry, a heptagon or septagon is a seven-sided polygon or 7-gon….Heptagon.

Regular heptagon
A regular heptagon
Type Regular polygon
Edges and vertices 7
Schläfli symbol {7}

### What is the measure of the interior angle of a 15 sided regular polygon Brainly?

Since the 15-gon is regular, this total is shared equally among the 15 interior angles. Each interior angle must have a measure of 2340 ÷ 15 = 156 degrees.

What is the sum of the interior angles of a 14 Gon?

154.3
By the Polygon Interior Angles Sum Theorem, the sum of the interior angle measures can also be expressed as . The measure of each interior angle of a regular polygon with 14 sides is about 154.3.

What is the sum of the measures of the interior angles of a 15?

2340 degrees
Each triangle has an angle sum of 180 degrees, so the sum of the interior angles of the 15-gon must be 13 × 180 = 2340 degrees.

## How many sides does 3060 have?

3060 over 180 3060 180 = 180 (n minus 2) over 180 180 (n − 2) 180 So the polygon has 19 sides. It is impossible to have a sum of 2400° for the interior angles of a convex polygon.

## How much does a 15 sided polygon add up to?

Since the polygon is regular, all sides and angles are equal, so each turn at each vertex is the same, and of size 360°15=24° degrees.

What is the sum of all exterior angle of a regular polygon?

360°
The sum of the exterior angles of a polygon is 360°.

What is the sum of exterior angles in a 15-gon?

The sum of the exterior angles in any convex polygon, including a regular 15-gon, is 360∘. What is the measure of the interior angle of a 15-Gon? What is the measure of each interior angle and exterior angle of a regular 15-Gon?

### How to find the sum of interior angles of a polygon with 15 sides?

Answer:A pentadecagon is a polygon with 15 sides. Each exterior angle of a regular pentadecagon = 360/15 = 24 deg, so each interior angle is 180–24 = 156 deg. And, the sum of the interior angles of a regular pentadecagon is 15*156 = 2340 deg.

### What is the sum of the interior angles of an octagon?

The sum of the interior angles in a regular polygon is given by the formula 180 (n – 2), where n is the number of sides in the polygon. An octagon has eight sides, so the sum of the angles of the octagon is 180 (8 – 2) = 180 (6) = 1080 degrees.

What is the sum of all angles of a hexagon?

So, the sum of the interior angles of a hexagon is 720 degrees. All sides are the same length (congruent) and all interior angles are the same size (congruent). To find the measure of the interior angles, we know that the sum of all the angles is 720 degrees (from above)…
