(i) 50° + 60° + x° = 180°
→ 110° + x° = 180°
→ x° = 180° - 110°
→ x° = 70°
----------------------------------------
(ii) 90° + 30° + x° = 180°
→ 120° + x° = 180°
→ x° = 180° - 120°
→ x° = 60°
----------------------------------------
(iii) 30° + 110° + x° = 180°
→ 140° + x° = 180°
→ x = 180° - 140°
→ x = 40°

THANKS IF I COULD HELP YOU BUT I'M SORRY BECAUSE I'M NOT AN ARMY!
Answer: HI AM AN ARMY ♥♥♥♥
Step-by-step explanation:
1 50° + 60° + x° = 180° (ANGLE SUM PROPERTY)
110° + x° = 180°
x° = 180° - 110°
x° = 70°
2 90° + 30° + X° = 180° (ANGLE SUM PROPERTY)
120° + X° = 180°
X° = 180° - 120°
X° = 60°
3 30° + 110° + X° = 180° (ANGLE SUM PROPERTY)
140° + X° = 180°
X° = 180° - 140°
X° = 40°
