Question

Transcribed Image Text:**Part B**
A path goes around a forest so that it forms the three sides of a triangle. The lengths of two sides are 550 m and 290 m. These two sides meet at an angle of 115°. A diagram is shown below.
*Diagram Description:*
The diagram depicts a triangle surrounding a forest area with two marked sides: one labeled as 550 m and the other as 290 m, with an included angle of 115°.
1. **Calculate the length of the third side of the triangle. Give your answer correct to the nearest 10 m.**
2. **Calculate the area enclosed by the path that goes around the forest.**
Inside the forest, a second path forms the three sides of another triangle named ABC. Angle BAC is 53°, AC is 180 m, and BC is 230 m.
