|Use the following scenario for all 5 questions: A newspaper ad refers to a plot of land for sale. The ad states that the land is in the shape of a triangle, with|

|one side measuring 8 miles, another side measuring 5 miles, and the angle opposite the 5 mile side measuring 30°. |

|Use the chart for the ambiguous case to determine how many different shapes could be represented. |
