Answer:
60
Step-by-step explanation:
From the question:
2 Cos x = 1
x =?
Thus, we can obtain the value of x as follow:
2 Cos x = 1
Divide both side by 2
Cos x = 1/2
Cos x = 0.5
Take the inverse of Cos.
x = Cos¯¹ (0.5)
x = 60
Therefore, the value of x is 60
**** Check ****
2 Cos x = 1
x = 60
2 Cos 60 = 1
2 × 0.5 = 1
1 = 1
