As illustrated, two dogs are dragging a sledge over an icy track. Dog X exerts a pull of $200\ \text{N}$ at an angle of $65^\circ$ to the front edge of the sledge. Dog Y exerts a pull of $120\ \text{N}$ at an angle of $45^\circ$ to the front edge of the sledge. What is the resultant forward force on the sledge exerted by the two dogs?
- A$80\ \text{N}$
- B$170\ \text{N}$
- C$270\ \text{N}$
- D$320\ \text{N}$
