Answer 1

the statement is false for any value of y
answer:y∈∅

Answer 2

y = 0.9

Explanation:

Given :
`Cos y = (8)/(13)`.

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

Solution : We have given

`Cos y = (8)/(13)`.

On taking the inverse of cos both sides .

y =
`Cos^(-1)((8)/(13))`

y = 0.90792

Up to nearest tenth 0 .9

y = 0.9

Therefore, y = 0.9
