Answer:
each interior angle = 150°
Step-by-step explanation:
(N x 180°) - 360° = the sum of interior angles
where N = the number of sides
(12 x 180°) - 360° = 1800°
Since it is a regular polygon, all 12 angles are equal:
1800°/12 = 150°
12 more than 8.2 times a number n is the same as “8.2n + 12”.
Angle C is 40degree
Then Angle B is supposed to be 180-90-40 which will be 50 degree
