Three small colorful starfish are located on the sea floor and are represented in the model by the points $P , Q$ and $R$. The photographer moves for his shots from the location described in the model by the point $K$, parallel to the sea floor. The camera lens points perpendicular to the sea floor and has a cone-shaped field of view with an opening angle of $90 ^ { \circ }$. Assess whether the photographer can reach a location in this way where he can see all three starfish simultaneously in the camera's field of view.
