Fine the missing value to the nearest hundredth cos=7/14

We are asked to solve a trigonometric function which is

cos θ = 7/14

To solve for θ, we get the inverse cosine of both sides resulting to

θ = cos⁻¹ (7/14)

θ = cos⁻¹ (0.5)

by special triangles or using the calculator, the value of the angle is

θ = 60°or in radians 1.54 radians
