$\mathfrak{\huge{\red{\underline{\underline{Answer→}}}}}$

(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°

----------------------------------------

Answer 2

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°
