answer:y∈∅

Answer 2

Answer:

y = 0.9

Step-by-step explanation:

Given : $Cos y = \frac{8}{13}$.

To find : Find the value of y. Round your answer to the nearest tenth.

Solution : We have given

 $Cos y = \frac{8}{13}$.

On taking the inverse of cos both sides .

y = $Cos^{-1}(\frac{8}{13})$

y = 0.90792

Up to nearest tenth 0 .9

y = 0.9

Therefore, y = 0.9
