Solution: Here, each interior angle = 165°
Hence, each exterior angle = 180° - 165° = 15°
As, measure of each exterior angle = 15°
So, number of sides = 360°/15° = 24
Hence, number of sides = 24
M is the molecular mass of NaCl crystal. And N is the Avogadro's number of atoms.
Since there are 2N ions in one gram molecule,
The mass associated with each ion =...
A regular polygon: A polygon having all sides of equal length and the interior angles of equal size is known as regular polygon.
(i) 3 sides
Polygon having three sides is called...
(i) 9 sides
Solution: Since, 9 sides of a polygon has nine angles
And we know that sum of exterior angles of a polygon = 360⁰
So, 9 exterior angles = 360°
Or, 1 exterior...
Solution:We know that number of angles of a polygon = number of sides
And we know that sum of exterior angles of a polygon = 360⁰
So, measure of each angle =...
Solution:
Since, number of sides of a polygon = 360°/each exterior angle
Hence, number of sides of given polygon = 360°/22° = 16.36
Since, answer is not a whole number, thus, a regular...
Solution: Here, each interior angle = 22°
Hence, each exterior angle = 180° - 22° = 158°
Hence, number of sides = 360°/158° = 2.27
Since, answer is not a whole number, thus, a...
Solution: (a) Triangle is the polygon with minimum number of sides and an equilateral triangle is a regular polygon because all sides are equal in this. We know that each...
(i) No, a polyhedron cannot have 3 triangles for its faces.
(ii) Yes, a polyhedron can have four triangles which is known as pyramid on triangular base.
(iii) Yes, a polyhedron has...
