1. The problem states that \( \frac{AC}{36} = \frac{60}{48} \). 2. To find \( AC \), we can cross-multiply: \( AC \times 48 = 60 \times 36 \). 3. Simplify the right side: \( 60 \times 36 = 2160 \). 4. So, \( 48 \times AC = 2160 \). 5. Divide both sides by 48 to isolate \( AC \): \( AC = \frac{2160}{48} \). 6. Calculate the division: \( AC = 45 \). Final answer: \( AC = 45 \).
