Question

Answer 1

Answer:  x = 7

Step-by-step explanation:  All the angles of a parallelogram add to 360°

Any two of the consecutive angles add to 180°

Using that information, we can create an equation with the angle measurements given:

(7x + 33) + (11x + 21) = 180 . Combine like terms:

7x + 11x + 33 + 21 =180

18x + 54 = 180 .  Subtract 54 from both sides

18x = 126   Divide both sides by 18

x = 7
