Answer:
The function would be positive in:
<u>(-9, 3]
</u>
Step-by-step explanation:
A function is considered positive on the X-axis when the changed values in the function are greater than zero. f(x) > 0
And is considered negative when f(x) < 0.
In this case, the numbers that make the function positive are the numbers from -9 to 3, but not including -9.
This can be written as (-9, 3]
It means that -9 is not taken but any number greater than -9 is.
First of all in order for us to figure out what angle x is we need to find the formula for finding that specific type of angle.
Formula is...
x = (far arc - close arc) ÷ 2
Now we just need to plug in.
x = (172° - 52°) ÷ 2 =
x = 120° ÷ 2 = 60°
Your answer: x = 60°
Good Luck! :)
