Answer 2

Answer:

(i) 120° = 30° + x ( exterior angle property )

120° - 30° = x

90° = x

Now,

30 + x + y = 180° ( angle sum property )

30 + 90 + y = 180°

120 + y = 180°

y = 180° - 120°

y = 60°

Hence x = 90° and y = 60°

(ii) 120° = 60° + y ( exterior angle property )

120° - 60° = y

60° = y

Now,

60 + y + x = 180° ( angle sum property )

60 + 60 + x = 180°

120 + x = 180°

x = 180° - 120°

x = 60°

Hence x = 60° and y = 60°
