Answer:
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
You can do addition and substraction operations with polynomials similarly as with simple real numbers.
First of all you have to open brackets and then you can add numbers (-7-4=-11). Then the result is following:
