Television Coverage

A television camera is on a reviewing platform 27 meters from the street on which a parade will be passing from left to right (see figure). Write the distance d from the camera to a particular unit in the parade as a function of the angle x, and graph the function over the interval −π/2 < x < π/2. (Consider x as negative when a unit in the parade approaches from the left.)
