The image contains 8 triangles, each with given sides and/or angles. These are most likely problems involving the Law of Cosines or Law of Sines, commonly used in trigonometry to find missing sides or angles in triangles.

### Let's break down the given problems:
1. **Triangle 1:**
   - Sides: \( AB = 6.7 \, \text{m}, AC = 8.6 \, \text{m}, BC = 13.7 \, \text{m} \)
   - Likely requires the use of the Law of Cosines or Heron’s formula (for area).
   
2. **Triangle 2:**
   - Sides: \( AB = 8 \, \text{mi}, AC = 10 \, \text{mi} \)
   - Angle: \( \angle ACB = 143^\circ \)
   - Use Law of Cosines to find the third side \( BC \).

3. **Triangle 3:**
   - Sides: \( AB = 11.8 \, \text{ft}, AC = 9 \, \text{ft} \)
   - Angle: \( \angle BAC = 43^\circ \)
   - Law of Cosines can be used to find side \( BC \).

4. **Triangle 4:**
   - Sides: \( AB = 7 \, \text{m}, BC = 15 \, \text{m}, AC = 16 \, \text{m} \)
   - This might require Law of Cosines to find an angle.

5. **Triangle 5:**
   - Sides: \( AB = 7 \, \text{yd}, BC = 7.3 \, \text{yd} \)
   - Angle: \( \angle ACB = 149^\circ \)
   - Law of Cosines can help determine side \( AC \).

6. **Triangle 6:**
   - Sides: \( AB = 11 \, \text{mi}, AC = 14 \, \text{mi} \)
   - Angle: \( \angle BAC = 120^\circ \)
   - Use Law of Cosines to find side \( BC \).

7. **Triangle 7:**
   - Sides: \( AB = 13 \, \text{ft}, BC = 8 \, \text{ft}, AC = 15 \, \text{ft} \)
   - This could involve Heron’s formula for area or verifying a right triangle using the Pythagorean theorem.

8. **Triangle 8:**
   - Sides: \( AB = 6 \, \text{ft}, BC = 6 \, \text{ft} \)
   - Angle: \( \angle ACB = 147^\circ \)
   - Use Law of Cosines to find side \( AC \).
