Question

three angles of a polygon ate right angles and each of the other is 150 degree then the number of sides of the polygon are​

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Number of sides of polygon are  6

Step-by-step explanation:

Let say Polygon has n number of sides

Sum of interior angles of n sides polygon = (n - 2) * 180°

= n(180)° - 360°

three angles are  right angle 90°  each

remaining n - 3 angles are  150°  each

Sum of all angles of polygon =   3* 90°  + (n-3)150°

= 270° + n(150)° - 450°

= n(150)° - 180°

n(150)° - 180° = n(180)° - 360°

=> n(30)° = 180°

=> n = 6
