Question

What is the sum of the interior angles of the polygon shown below?​

Answer 1

Answer:

x = 121°

y = 40°

z = 19°

Step-by-step explanation:

z = 19° [Alternate angles]

x = 121°[Opposite angles of a parallelogram are equal]

<ABD = y [Alternate interior angle]

<ABD + 121° + z =180° [Angle sum property]

<ABD + 121° + 19° = 180°[z= 19°]

<ABD + 140° = 180°

<ABD = 180° - 140°

<ABD= 40°

so, y = 40°

hope it's correct !!
