What is the cos x =1.7%2 and x is acute angle

Given :

cos x = 1.7/2 .

Also, x is an acute angle.

To Find :

The value of angle x.

Solution :

cos x = 1.7/2

Applying cos inverse both the sides, we get :

Calculating the value of   from calculator, we get :

x = 31.79°

Therefore, the acute angle x is 31.79°.
