Correct answer
Atan-132

Step-by-step explanation

Given here, θ'=60° and apparent value of dip, α=45°.

If H is horizontal component of earth's magnetic field in magnetic meridian, then tanθ'=VH.

Let H1 be component of H at 60° to magnetic meridian, then tanθ=VH1=VHcosα=tanθ'cosα

tanθ=tan60°×cos45°

⇒tanθ=3×12

Thus, the actual value of the angle of dip is θ=tan-132
