Which, among the following, is the correct expression for φ.
A woman stands at a horizontal distance x from a mountain and measures the angle of elevation of the mountaintop above the horizontal as θ. After walking a distance d closer to the mountain on level ground, she finds the angle to be Φ. Find a general equation for the height y of the mountain in terms of d, Φ, and θ, neglecting the height of her eyes above the ground.
