Question

Can you tell me these answer Please ​

Answer 1

first one is 105 and second one is 4

Answer 2

11.

i ) x + 41° + 105° + 130° = 360°

x + 276° = 360°

x = 360° - 276° = 84°

ii) 3x + x + 40° = 180°

4x + 40° = 180°

4x = 180° - 40° = 140°

x = 35°

iii) 2x + 10° + 3x - 10° + 40° = 180°

5x + 40° = 180°

5x = 180° - 40° = 140°

x = 28°

12.

i) x + 135° = 180°

x = 180° - 135° = 45°

x + y = 180°

45° + y = 180°

y = 180° - 45° = 135°

y + z = 180°

135° + z = 180°

z = 180° - 135° = 45°

Hence , x = 45°

y = 135°

z = 45°
