How many sides does a regular polygon have if the measures of the interior angle is 60 degrees?
base on (n-2)*180=the sum of all the interior angle and ext.angle +int angle =180 mean the ext angle =120 ext angle sum up to 360 360/120=n n=3 n stand for sides
What is the missing angle of a triangle of 35degree's and 25degree's?
The sum of the angles in a triangle add up to 180. So in this case 180-35-25=120. The missing angle in this problem is 120 degrees.
What is the sum of the measures of the interior angle of a regular polgon if each exterior angle measures 120?
180
What is the sum of the measures of the interior angle of a regular plygon if each exerior angle measures 120?
The sum of the exterior angles is 360 so if each is 120 we know 360/120=3. This tells us there are 3 exterior angles. The sum of the interior angles in a triangle is 180 degrees.
What is sum of the exterior angle of a 120-sided regular plygon?
360 degrees
What is the sum of the angle in a hexagon?
180 + 180 * 3 = 720 Each angle inside a hexagon is 120 degrees.
The sum of an interior angle and an exterior angle of regular hexagon equals?
Interior is 120 degrees Exterior is 60 degrees.
How many degrees are in the sum of an interior angle and exterior angle of a regular hexagon?
Int 120, ext 60
What is the sum of the measures of the interior angles if each exterior angle measures 120?
180
What is the proof that the sum of the angles of a hexagon equals 720?
There are 6 angles in a hexagon, and each angle measures 120 degrees. 120 x 6, or 120+120+120+120+120+120=720.
What is the measurement of the fourth angle of a quadrilateral if the others measure 60 120 and 90?
The sum of the angles in a quadrilateral is always 360 degrees. Given the three angles measuring 60, 120, and 90 degrees, their sum is 60 + 120 + 90 = 270 degrees. To find the fourth angle, subtract this sum from 360 degrees: 360 - 270 = 90 degrees. Therefore, the measurement of the fourth angle is 90 degrees.
What is the sum of the measures of the interior angle of a regular plygon if each exerior angle measures 120 degrees?
It will have 3 interior angles of 60 degrees that add up to 180 degrees and it is an equilateral triangle.
