Answer
In a parallelogram, opposite angles are equal.
⇒ (6x - 17)° = (x + 63)°
⇒ 5x° = 80°
⇒ x° =
⇒ x° = 16°
Then, first angle = (6x - 17)°
= (6 16 - 17)°
= (96 - 17)°
= 79°
Second angle = 180° - 79° = 101°
In a parallelogram, consecutive angles are supplementary, meaning their sum is 180°. So, the other pair of opposite angles is:
180° - 79° = 101°
Hence, the four angles of the parallelogram are 79°, 101°, 79° and 101°.
