Solve equation. Show steps

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
