The other angle measures 112°.
All the angles in any 4-sided polygon will add up to 360°, like how all angles in a triangle add up to 180°. A good way to remember this is with the sum of interior angles formula:
180 x (n - 2), where n is the number of sides.

Answer:
-5
Step-by-step explanation:
We need to eliminate 22, so x is alone.
2x+22=12
So we subtract 22 from both sides.
2x+22=12
-22 -22
2x=-10
Now we have to divide 2 on both sides so x is alone.
2x=-10
÷2. ÷2
x=-5
We can always check
2(-5)+22=12
-10+22=12
12=12
