Question

If the possible to have a polygon of the sum of whose interior angle is 870 , 2340,7right angles​

Answer 1

Let no. of sides = n  Sum of angles = 870°  (n – 2) x 180° = 870°  n – 2 = 870/180 n – 2 = 29/6 n = 29/6 + 2  n = 41/6 Which is not a whole number. Hence it is not possible to have a polygon, the sum of whose interior angles is 870°
