Answer:

b

Step-by-step explanation:

∠ BDC + ∠ ADC = ∠ ADB , substitute values

- 6x + 53 - 9x + 22 = 90

- 15x + 75 = 90 ( subtract 75 from both sides )

- 15x = 15 ( divide both sides by - 15 )

x = - 1

Then

∠ ADC = - 9x + 22 = - 9(- 1) + 22 = 9 + 22 = 31° → b

Step-by-step explanation:

p(x) = |x|

in : R  let : y = |x|
