Question

Find the number of sides of regular polygons in each interior angle is 60 degree


pls solve this sum pls all my bothers and sisters

Answer 1

the number of sides is 3

Answer 2

interior angle of a regular polygon = [(no. of sides - 2) x 180] / no.of sides

                                                         = 60°

(no.of sides=n)

∴[(n-2) x 180] / n = 60

(180n - 360) = 60 n

-360 = 60n- 180n

-360= -120n

∴n= -360/-120

  = 3

will you mark this as brainliest if it is correct? please?
