Question

The options for the first blank are 45, 240, 270, and 315

The options for the second blank are 225, 315, 450, 630

Answer 1

The solutions are 270° and 450°.

Explanation:

Given:

`cos(x)/(2) =(√(2) )/(2)`.

So, the second and third quadrant angle to be calculated.

`cos(x)/(2)=135`

`=x=270`°.

And,
`cos(x)/(2)=225`

`=x=450`°

Therefore, the solutions are 270° and 450°.
