Answer» It's a property of parallelogram that opposite angles of a parallelogram are equal. Therefore , angle A = angle C 3x + 20° = 2x + 70° 3x - 2x = 70° - 20° x = 50° Therefore, angle A = angle C = 3 × 50° + 20° = 170° And angle B = angle D = 180° - 170° = 10° Hence, 170° and 10° are the angles.

Answer»

It's a property of parallelogram that opposite angles of a parallelogram are equal.

Therefore , angle A = angle C

3x + 20° = 2x + 70°

3x - 2x = 70° - 20°

x = 50°

Therefore, angle A = angle C = 3 × 50° + 20° = 170°

And angle B = angle D = 180° - 170° = 10°

Hence, 170° and 10° are the angles.
