#9-i
each exterior angle of the polygon ; (ii) number of sides in the polygon (ii) number of sides in the polygon
Ans : x = 60˚
∴ Each exterior angle = 60˚
Let angle of sides = n
∴ 360˚/n = 60˚
⇒ n = 360˚/60˚
dlt29025704036958965620">⇒ n = 360˚/60˚ (ii) n = 6
∴ (i) 60˚ (ii) 6 (ii) n = 6
∴ (i) 60˚ (ii) 6

#9-ii
number of sides in the polygon
Ans : n = 6
∴ (i) 60˚ (ii) 6
