Question

 If sec x = 2, then the value of x is​

Answer 1

Sec x=2

Cos x = 1/2

so,x=60°

Answer 2

Given : The value of sec x is 2

To find : The value of x

Solution :

We can simply solve this mathematical problem by using the following mathematical process. (our goal is to calculate the value of x)

Here, we will be using general trigonometric identities and predefined values of some trigonometric angles.

So,

sec (x) = 2

$\frac{1}{ \cos(x) } = 2$

$2 \cos(x ) = 1$

$\cos(x ) = \frac{1}{2}$

$\cos(x) = \cos(60°)$

which implies,

$x = 60°$

(This will be considered as the final result.)

Hence, the value of x is 60°
