Answer:
x= 305.541
Step-by-step explanation:
To solve the equation cos ([tex]\frac{1}{3}[/tex]x)= -0.23 you need to find the value of x. Here's how you can do it:
1. Begin by isolating [tex]\frac{1}{3}[/tex]x:
cos([tex]\frac{1}{3}[/tex]x)= -0.23
2. Take the inverse cosine of both sides to isolate [tex]\frac{1}{3}[/tex]x:
[tex]\frac{1}{3}[/tex]x = arcoss (-0.23)
3. Multiply both sides by 3 to solve for x:
x=3 · arcoss (-0.23)
arcoss(-0.23) = 101.847
Now, multiply this angle by 3 to find:
x= 3 · 101.847
x= 305.541
