1. **Problem statement:** JK is tangent to the circle at point L. The arc LM measures 114° and the angle formed between the tangent JK and chord LM at point L is given as (21x - 24)°. We need to find the value of $x$.
2. **Formula and rule:** The angle between a tangent and a chord is equal to half the measure of the intercepted arc. This means:
$$\text{Angle at } L = \frac{1}{2} \times \text{Arc } LM$$
3. **Set up the equation:**
$$21x - 24 = \frac{1}{2} \times 114$$
4. **Calculate the right side:**
$$\frac{1}{2} \times 114 = 57$$
5. **Solve for $x$:**
$$21x - 24 = 57$$
$$21x = 57 + 24$$
$$21x = 81$$
6. **Divide both sides by 21:**
$$x = \frac{81}{21}$$
7. **Simplify the fraction:**
$$x = \frac{\cancel{81}^{3 \times 27}}{\cancel{21}^{3 \times 7}} = \frac{27}{7} \approx 3.857$$
**Final answer:**
$$x \approx 3.86$$
