360/24 = 15 sides.

A triangle with interior angles of 42, 87 and 24 degrees doesn't exist because the angles add up to 153 degrees whereas the interior angles of any triangle always add up to 180 degrees.

Interior angle 156 degrees Exterior angle 24 degrees 360/24 = 15 sides

3 x ? =24

The formula for finding the interior angle of any shape is: [180*(n-2)]/n, with n being the number of sides you have.In your case, you have a 24-gon. Plug it in for your n, and you have[180*(24-2)]/24 -> [180*22]/24 -> 3960/24 -> 165So the interior angle would be 165o.

The answer is 24!!!360 divided by 15 equals 24.

False : Cos B = 16.67/24 = 0.6946 : Therefore angle B = 46° (not 26°).

360/24 = 15 sides.

It will have 360/24 = 15 sides

The central angle of a n-sided regular polygon = 360 degrees / n. Hence, the central angle of a 15-sided regular polygon = 360 degrees / 15 = 24 degrees ============================

A triangle with interior angles of 42, 87 and 24 degrees doesn't exist because the angles add up to 153 degrees whereas the interior angles of any triangle always add up to 180 degrees.

Angle equals the ArcTangent of (24 /72 ) or = ArcTangent (1/3) Angle is 18.42 degrees. The other larger angle is 71.58 degrees. Link for ArcTangent Calculator: http://www.analyzemath.com/Calculators_2/arctan_calculator.html

360/15 = 24 sides

Exterior angle = 360/number of sides = 360/15 = 24 degrees.Interior angle = 180 - Exterior angle = 180 - 24 = 156 degrees.Angle at centre = Exterior angle = 24 degrees.Exterior angle = 360/number of sides = 360/15 = 24 degrees.Interior angle = 180 - Exterior angle = 180 - 24 = 156 degrees.Angle at centre = Exterior angle = 24 degrees.Exterior angle = 360/number of sides = 360/15 = 24 degrees.Interior angle = 180 - Exterior angle = 180 - 24 = 156 degrees.Angle at centre = Exterior angle = 24 degrees.Exterior angle = 360/number of sides = 360/15 = 24 degrees.Interior angle = 180 - Exterior angle = 180 - 24 = 156 degrees.Angle at centre = Exterior angle = 24 degrees.

The sum of exterior angles always equals 360 degrees. Therefore, 360 degrees/24 angle = 15 degrees per angle. Keep in mind this only works for regular polygons.
