Question

given figure a b parallel to CD then the value of X Y and Z are​

Answer 1

Answer:

x = 20°   z = 120°    y = 60°

Step-by-step explanation:

3x° + 2x° + 80° = 180°                                  ...... interior angles

From above,

5x = 100°

∴ x = 20°

3x + z = 180°                                                 ... interior angles

3(20)° + z = 180°

60° + z = 180°

∴ z = 120°

y + z = 180°                                                  ... Linear Pair of angles

y + 120° = 180°

∴ y = 60°
