A cable-stayed bridge is similar to a suspension bridge but is more efficient for medium distances. In this design of the bridge, there are two towers and strong cables attach to the tops of the towers and the sides of the bridge. Assume the bridge is perpendicular to the two towers.
Angle A is 35 degrees. Explain how you can find the measure of angles B, C and D ( all the angles in a triangle add to 180 degrees) Can you find the measure of every angle on the bridge?
The fourth shortest cables are 115 meters long. Each successive cable is 32 meters longer than the one below it. How much cable is needed to make the bridge??
