Question

please give me answer step by step.​

Answer 1

Answer:

it's a parallelogram

Step-by-step explanation:

in parallelogram

1.opposite angles are equal

• so x=y

2.sum of adjesent angles is 180°

• x+40=180
• x=180-40
• x=140°
• x=y=140

3.in transversal (here) angle y=angle z

• z=140°

one small note you drawn the diagram in wrong way!

Answer 2

Answer:

∠Y =40°....{CORRESPONDING ANGLES}

∠40°+∠X = 180°....{INTERNAL ANGLE}

∴∠X=180-40

∴∠X=140°

∠X=∠Z....{ALTERNATE ANGLE}

∴∠Z=140°

∴∠X=140°, ∠Y =40°, ∠Z=140°
