With any regular polygon it is 180 minus interior angle times number of sides equals 360 degrees

The regular polygon has 36 sides. Check: Exterior angle=360/36=10 degrees Interior angle=34*180/36=170 degrees. 170 is 17 times larger than 10 so 36 sides is the correct answer. Method: 180n-360=17*180 180n=6480 n=36

17x+x=180 degrees as interior+exterior angle = 180 degrees. 18x=180 so x=10, this is the exterior angle. 360/10=36, this is the number of sides. Check: 34*180/36=170 degrees which is 17 times larger than 10 so this answer is correct.

Each interior angle of a regular polygon has a measure that is equal to one hundred and eighty degrees times two less than the number of sides in the polygon.

Providing that it is a regular polygon it will have 8 sides.

If interior angles are 177o then exterior angles are 3o. Exterior angle times number of sides is always 360 so the polygon has 120 sides.

Interior angle + Exterior angle = 180 So Interior angle = 180 - Exterior angle Interior angle = 4*Exterior angle + 30 Substitute for Interior angle: 180 - Exterior angle = 4*Exterior angle + 30 Collect like terms: 150 = 5*Exterior angle Divide by 5: Exterior angle = 30 deg Therefore number of sides = 360/30 = 12

It will have 10 sides and each interior angle measures 144 degrees while each exterior angle measures 36 degrees

The measure of an interior angle in degrees of a regular polygon of n sides is given by the formula: 180 x (n-2) / nThe measure of an exterior angle in degrees of a regular polygon of n sides is given by the formula: 360/nIf the interior angle is 11 times the exterior angle, then:180 (n-2)/n = 11 x 360/nthen: 180 n - 360 = 11 x 360, or180 n = 12 x 360that its solution gives n = 24Accordingly, the answer is that the number of sides of this polygon is 24

With any regular polygon it is 180 minus interior angle times number of sides equals 360 degrees

Suppose the interior angle is x degrees. Then the exterior angle is 180 - x degrees. x = 5*(180-x) = 900 - 5x So 6x = 900 so that x = 150 degrees. So exterior angle = 30 degrees. If the polygon has n sides (and n angles) the sum of its exterior angles is 30*n But the exterior angles of a polygon add to 360 degrees So 30*n = 360 so that n = 12. ANSWER: 12 sides.

The regular polygon has 36 sides. Check: Exterior angle=360/36=10 degrees Interior angle=34*180/36=170 degrees. 170 is 17 times larger than 10 so 36 sides is the correct answer. Method: 180n-360=17*180 180n=6480 n=36

360/number of sides 180 times the number of sides the polygon has then minus 360. This gives the total sum of the exterior angles. Then to get the angle of one exterior angle divide it by the number of sides the polygon has.Very easy when you know the formula!

17x+x=180 degrees as interior+exterior angle = 180 degrees. 18x=180 so x=10, this is the exterior angle. 360/10=36, this is the number of sides. Check: 34*180/36=170 degrees which is 17 times larger than 10 so this answer is correct.
