Question

3. Find the number of sides of a polygon whose exterior and interior angles are in the ratio 1:5.
4. Two regular polygons are such that the ratio between their number of sides is 1 : 2 and the ratio of measure
of their interior angles is 3:4. Find number of sides of each polygon.
A​

Answer 1

Answer:

3=12

4

Step-by-step explanation:

3=we know that the sum of one exterior angle and one interior angle is 180deg

Exterior angle is x

Given 1:5

X+5x=180

6x=180

X=30

Now the sum of exterior angle in polygon =360

Nx=360

N*30=360

N=12

Answer 2
