Question

1.
(3x + 12)
(11x)
This is geometry could plz help me

Answer 1

12

Explanation:

( 3x + 12 ) + 11x = 180°

14x = 180 - 12

14x = 168

x = 168÷14

x = 12

Answer 2

x = 12°

Explanation:

3x + 12° + 11x = 180° {being co-interior angles }

12° + 14x = 180°

14x = 180° - 12°

14x = 168°

x = 168° / 14

x = 12°
