Answer:

h = 18.

z = 54.

Step-by-step explanation:

Form 2 equations:-

z = 3h    ( because opposite angles in a parallelogram are equal)

z + 7h = 180  ( because inside angles add up to 189 degrees).

Substitute  z = 3h in the second equation:

3h + 7h = 180

10h = 180,  so h = 18.

Therefore  z = 3h = 54.
