To measure the length \( d \) of a lake (see Fig. 7), a baseline \( AB \) is established and measured to be 125 meters. Angles \( A \) and \( B \) are measured to be 41.6° and 124.3°, respectively. How long is the lake? **Diagram Explanation:** The diagram shows a triangular field setup for measuring the length of the lake. The key elements are: - **Baseline \( AB \):** This is a straight line with a known length of 125 meters. - **Point \( C \):** The opposite point forming the triangle with the baseline. - **Angles:** - \( \angle CAB = 41.6^\circ \) at point \( A \). - \( \angle ABC = 124.3^\circ \) at point \( B \). The unknown length \( d \) is the distance from point \( B \) to \( C \), representing the length of the lake. The diagram indicates a clear view across the lake to aid in measuring and calculating \( d \).
