1440 degrees. The total exterior angles of a polygon is always 360 deg. Each interior angle plus its corresponding exterior angle is 180 deg. The sum of all interior plus all interior for a decagon must therefore be 1800 deg. Hence sum of interior angles is: 1800-360=1440 deg.

What is the sum of the interior angles of this decagon?
1440
What is the sum of the interior angles of a regular decagon?
1440 degrees. The sum of the interior angles of any regular polygon of n sides is equal to 180(n - 2) degrees.
What is the measure of an interior angle for a regular ten-sided polygon?
144o. Sum of exterior angles of a polygon is 360o. Each exterior angle for a regular decagon is 360o / 10 = 36o. Exterior and interior angles are supplementary, that is sum to 180o. Therefore the interior angle of a regular decagon is 180o - 36o = 144o.
How many angles does a decagon have?
A decagon has 10 angles (and sides)
What is the angle measure of each interior angle of a regular decagon?
The angle measure for each interior is 144 degrees each.Explanation: The angle measure of each interior angle of a regular decagon is 144°. Since a decagon is a 10-sided figure, replace n by 10 in (n − 2) • 180°. So the sum of the interior angle measures in a decagon is (10 − 2) • 180°, or 8 • 180° = 1440°. This is a regular decagon, so all ten interior angles are congruent. To calculate the measure of each interior angle in this regular decagon, divide 1440 by 10. The answer is 144°. 144 degrees is equal to 4/5 of 180 degrees
How many degrees total in the angles of a duo-decagon?
The sum of the interior angles of a dodecagon (not duo-decagon) is (12 - 2)*180 = 1800 degrees.
What is the SUM of ALL of the interior angles of a decagon?
The 10 interior angles of a decagon add up to 1440 degrees
What is the sum of the measrures of the interior angles of a decagon?
The interior angles of a 10 sided decagon add up to 1440 degrees.
What is the answer to the interior angles in a decagon?
The sum of the interior angles in a decagon = 180(10-2) = 1440° The measure of a single interior angle in a decagon = (180(10-2))/10 = 144°
What is the difference in the sum of the interior angles of a decagon compared to a triangle?
The sum of the interior angles of a decagon is 1440 degrees The sum of the interior angles of a triangle is 180 degreesThe difference in the sum of the interior angles of a decagon compared to a triangle = 1440 degrees minus 180 degrees = 1260 degrees
What is the sum of the angles measured in a decagon?
The 10 interior angles of a decagon add up to 1440 degrees
What is the sum of the interior angles of this decagon?
1440
How many acute angles in a decagon?
A decagon is a polygon with 10 sides. In a decagon, each interior angle measures 144 degrees. An acute angle is an angle that measures less than 90 degrees. Since all the interior angles of a decagon are 144 degrees, there are no acute angles in a decagon.
Does a decagon have right angles?
Not normally but if it was an irregular decagon then it's quite possible.
How many sides and angles does a decagon have?
A decagon has 10 sides, and 10 angles. The sum of the interior angles of a decagon is (10-2)×180° = 1440° In a regular decagon all the angles are congruent at 1440° ÷ 10 = 144°
What is the sum of the measures of the interior angles of a decagon?
1440
How many degrees are in a decagon if 3 angles equal 200 degrees?
A decagon will always have its interior angles measure 1480
