Please answer whole question

A lighthouse stands 650 m off a straight shore and the focused beam of its light revolves five times each minute. As shown in the figure, P is the point on shore closest to the lighthouse and Q is a point on the shore 350 m from P. What is the speed of the beam along the shore when it strikes the point Q? Lighthouse 350 m- P 650 m Let x be the distance along the shore from point P to the beam and let O be the angle through which the light revolves. Write an equation that relates x and
