A closed circle means that value is included, and an open circle means that value is excluded.
Example:
x > 2 ---- Graphed with an open circle, everything greater than but not including 2
x ≤ 3 ------ Graphed with a closed circle, everything less than and including 3

Answer:
x ≈ 13.4
Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to remind you of the relationships between trig functions and sides of a right triangle.
__
The figure shows a marked angle (33°), the side adjacent (x), and the hypotenuse (16). The relevant trig relation is ...
Cos = Adjacent/Hypotenuse
cos(33°) = x/16 . . . . . . substitute given values
x = 16·cos(33°) . . . . . multiply by 16
x ≈ 13.419 . . . . . . . . evaluate
The value of x is approximately 13.4.
Ok I’m so sorry I can’t answer this but if no one does then check out wolframalpha.com
That’s where I used to get all my answers from cuz it can solve almost any mathematical problem! <3
Hope that helps in a way!
