What’s the answer to this question?

x=9

adjacent angles

Step-by-step explanation:

we can set up an equation because if we add these angles, we will get our 90 degree angle,

  lets solve for x, first add like terms,

9x+9=90,   subtract 9 from both sides,         9x+9-9=90-9,      9x=81

divide both sides by 9 and we get 9, so x=9

These are adjacent angles because adjacent angles are angles that are right next to each other. They can form a bigger angle because they are right next to each other

it is x equals 3   plese mark me really need it

step-by-step explanation:

b, i believe, but not sure.
