1. **Problem Statement:** We are given a circle with a chord of length 5, and a point outside the circle connected to the circle by two segments of lengths 4 and 3. We need to find the length $x$ of the segment extending from the circle to the external point. 2. **Relevant Theorem:** The Power of a Point theorem states that for a point outside a circle, the product of the lengths of the segments from the point to the circle along one secant equals the product along another secant. Mathematically, if the segments are $a$ and $b$ on one secant, and $c$ and $d$ on another, then: $$a \times b = c \times d$$ 3. **Applying the theorem:** Here, one secant has segments 4 and 3, so their product is: $$4 \times 3 = 12$$ The other secant has segments 5 (the chord) and $x$ (the unknown segment), so: $$5 \times x = 12$$ 4. **Solving for $x$:** $$x = \frac{12}{5} = 2.4$$ 5. **Checking the options:** None of the options directly show 2.4, but let's verify if any option matches $x$. Options: A. $\frac{15}{4} = 3.75$ B. $9$ C. $4$ D. $\frac{20}{3} \approx 6.67$ None match 2.4, so let's reconsider the problem setup. 6. **Re-examining the problem:** The chord length is 5, and the external point connects to the circle with segments 4 and 3. The segment $x$ extends from the circle to the external point along the chord's extension. Using the Power of a Point theorem for a tangent and a secant: If the tangent segment length is $x$, and the secant segments are 4 and 3, then: $$x^2 = 4 \times 3 = 12$$ 7. **Solving for $x$ in this case:** $$x = \sqrt{12} = 2\sqrt{3} \approx 3.464$$ 8. **Comparing with options:** A. $\frac{15}{4} = 3.75$ (close) C. $4$ The closest is option A, $\frac{15}{4}$. **Final answer:** A. $\frac{15}{4}$
