It’s 6 my bad if I’m wrong
Answer:
x = 45°
Step-by-step explanation:
The total measurement is 360° (the measurement of a circle).
Set the equation. Set all measurements equal to 360:
228 + (x + 29) + (x + 13) = 360
Combine like terms:
228 + 29 + 13 + 2x = 360
2x + 270 = 360
Isolate the variable, x. Note the equal sign, what you do to one side, you do to other. Do the opposite of PEMDAS. First, subtract 270 from both sides:
2x + 270 (-270) = 360 (-270)
2x = 360 - 270
2x = 90
Next, divide 2 from both sides of the equation:
(2x)/2 = (90)/2
x = 90/2
x = 45
x = 45° is your answer.

Answer:
domain: all real numbers
range: y ≥ -5
Step-by-step explanation:
The domain of any polynomial function is "all real numbers."
This polynomial is of even degree and has a positive leading coefficient. It will have a minimum value, but no maximum. We can get an idea of the minimum value by looking at the vertex form.
f(x) = x^4 -2x^2 -4
f(x) = (x^4 -2x^2 +1) -5 = (x^2 -1)^2 -5
The squared term will have a minimum value of 0, so the minimum of f(x) is -5.
The range is all real numbers greater than or equal to -5.
