Answer:
Step-by-step explanation:
(i) Hexagon
Numbers of sides, n=6
Sum of the interior angles =(2n–4)90
0
=((2×6)–4)×90
0
=(12–4)90
0
=8×90
0
=720
0
ii) Decagon
Numbers of sides, n=10
Sum of the interior angles =(2n–4)90
0
=((2×10)–4)×90
0
=(20–4)90
0
=16×90
0
=1440
5) x /70 = 20/140
x = 20/140 x 70
x = 10
