SpletThe sum of the exterior angles of a polygon is 360°. The formula for calculating the size of an exterior angle in a regular polygon is: 360 \(\div\) number of sides. SpletTwo angles are said to be supplementary if the sum of their measures is equal to 180o. The supplement of an angle can be found by subtracting that angle from 180o. Now in the …
Splet15. nov. 2024 · The exterior angle of the polygon = 72°. Let x represent the measure of an interior angle of the polygon. The sum of the exterior angle and the adjacent interior angle … SpletWhat is the measure of 1 exterior angle of a pentagon? Show Answer. This question cannot be answered because the shape is not a regular polygon. Although you know that sum of the exterior angles is 360, you can only use formula to find a single exterior angle if the polygon is regular!
Splet02. feb. 2024 · An exterior angle of a triangle is equal to the sum of the opposite interior angles. Every triangle has six exterior angles (two at each vertex are equal in measure). The exterior angles, taken one at each vertex, always sum up to 360 ° 360\degree 360°. An exterior angle is supplementary to its adjacent triangle interior angle. SpletThe exterior angle of a regular polygon is $40$ degrees, how many sides does it have? Ask Question Asked 7 years, 5 months ago. ... A regular polygon with an exterior angle measure of 40 degrees has nine sides. Every polygon's exterior angle sum equals 360. So 360/40 equals nine. Share.
Splet07. maj 2024 · So you can find the size of the exterior angles of a regular polygon quite easily: If there are #18# sides # (n=18)#, then each exterior angle is: # (360°)/n = …
Splet05. jun. 2024 · the sum of the exterior angles is ALWAYS 360° So you can find the size of the exterior angles of a regular polygon quite easily: If there are 18 sides (n = 18), then each exterior angle is: 360° n = 360° 18 = 20° The sum of the exterior and interior angles is 180° because they are adjacent angles on a straight line. dbt information for clientsSpletSolution: Irrespective of the number of sides of a regular polygon, the measure of each exterior angle is equal and the sum of the measure of all the exterior angles of the regular polygon is equal to 360°. (i) 9 sides. The total sum of all exterior angles = 360°. Each exterior angle = Sum of exterior angles / Number of sides. ge dishwasher motherboardSplet29. maj 2024 · The measure of an exterior angle of a triangle is always C. greater than either remote interior angle. This is due to the fact that an exterior angle is equivalent to the sum of the measures of two non - adjacent interior angles or … dbt information pdfSpletThe measure of exterior angle = Sum of two opposite interior angles’ measure What is the exterior angle Inequality Theorem? According to the exterior angle inequality theorem, the measure of an exterior angle of a … dbt informed treatmentSplet07. maj 2024 · So you can find the size of the exterior angles of a regular polygon quite easily: If there are #18# sides # (n=18)#, then each exterior angle is: # (360°)/n = (360°)/18 = 20°# . The sum of the exterior and interior angles is #180°# because they are adjacent angles on a straight line. dbt informed therapySpletSolution Verified by Toppr In a regular decagon, all sides are same size and measure of all interior angles are same. The sum of interior angles of decagon is (n−2)×180 o where n is number of sides of polygon. (10−2)×180 o=1440 o here n=10 because deca means 10 Each interior angle =1440/10=144 o ge dishwasher moldSpletThe Exterior Angle is the angle between any side of a shape, and a line extended from the next side. Another example: When we add up the Interior Angle and Exterior Angle we get a Straight Angle (180°), so they are "Supplementary Angles". The Exterior Angle is the angle between any side of a shape, and a line extended from … How to remember which is which?
