Answer:
36 degrees
Step-by-step explanation:
There's 180 degrees in a triangle.
Since they're supplementary angles, we do 180-142=38.
We now know that 106+38+x=180.
Solve for x: x=36
Answer: 0
Step-by-step explanation:
Simplifying
9x2 + 49x = 22 + -5x
Reorder the terms:
49x + 9x2 = 22 + -5x
Solving
49x + 9x2 = 22 + -5x
Solving for variable 'x'.
Reorder the terms:
-22 + 49x + 5x + 9x2 = 22 + -5x + -22 + 5x
Combine like terms: 49x + 5x = 54x
-22 + 54x + 9x2 = 22 + -5x + -22 + 5x
Reorder the terms:
-22 + 54x + 9x2 = 22 + -22 + -5x + 5x
Combine like terms: 22 + -22 = 0
-22 + 54x + 9x2 = 0 + -5x + 5x
-22 + 54x + 9x2 = -5x + 5x
Combine like terms: -5x + 5x = 0
-22 + 54x + 9x2 = 0
