It's a simple right angle trigonometry problem. You are given the length of one of the sides and an angle (though in a somewhat roundabout way). Hypotenuse is the distance from the camera to the rock. Pick a trig function to solve for the other side and hypotenuse.

Draw a sketch

tan 13.9 deg = 197 cm / distance
