Question

please somebody help solution of question no n​

Answer 1

_______________☆______________

z + 128° = 180° ...(linear pair)

z = 180 - 128

z = 52°

x + 140° = 180° ...(linear pair)

x = 180° - 140°

x = 40°

y = 88° ...(vertically opposite angles)

Verification :

• x + y + z = 180°...(angle sum property)
• 40° + 88° + 52° = 180°
• 90° + 88° = 180°
• 180° = 180°
