Did I calculate #4 correctly and could you help me with #5. This is APEX Math 2 Practice: Pendulums and Bridges3.6.4

4. Use the definition of slope to calculate the exact rise of the bridge, y. (3 points: 2 points for work, 1 point for the solution) 0.06 = le Rise Length of Run W Bridge 35+502 2509 50 Va + 50 = 50. 08 992 Length of bridge is 50.08 Va + 2500 approximately. 5. How long is the deck of the bridge? Show how you calculated r. (3 points: 2 points for work, 1 point for the solution)
