5 SECURITY An important bridge crosses a river at a key location Because it is so important robotic security cameras are placed at the locations of the dots in the figure Each robot can scan x degrees On the lower bank it takes 4 robots to cover the full angle from the edge of the river to the bridge On the upper bank it takes 5 robots to cover the full angle from the edge of the river to the bridge Bridge upper bank lower bank a How are the angles that are covered by the robots at the lower and upper banks related Derive an equation that x satisfies based on this relationship b How wide is the scanning angle for each robot What are the angles that the bridge makes with the
