Question

0 degrees is less than or equal to x which is less than or equal to 360 degrees. Cos x=1/2

Answer 1

x = 60°

Explanation:

Given that,

`\cos x = (1)/(2)`

We need to find the value of x.

We know that,
`\cos (60)=(1)/(2)`

So,

`\cos x = \cos(60)`

Equating both sides, we get :

`x=60^(\circ)`

Hence, the value of x is equal to 60°.
