What is the value of x?
Ronch [10]

Answer:

x = 10

Step-by-step explanation:

Consecutive angles in a parallelogram are supplementary, thus

∠ A + ∠ B = 180, substitute values

9x + 8 + 8x + 2 = 180, that is

17x + 10 = 180 ( subtract 10 from both sides )

17x = 170 ( divide both sides by 17 )

x = 10
