Answer:
y = 0.9
Step-by-step explanation:
Given : [tex]Cos y = \frac{8}{13}[/tex].
To find : Find the value of y. Round your answer to the nearest tenth.
Solution : We have given
[tex]Cos y = \frac{8}{13}[/tex].
On taking the inverse of cos both sides .
y = [tex]Cos^{-1}(\frac{8}{13})[/tex]
y = 0.90792
Up to nearest tenth 0 .9
y = 0.9
Therefore, y = 0.9
