Best ResponseYou've already chosen the best response.0One corresponding side is JH~QS. The proportion is \[\frac{ 66 }{ 72 }\]. Also, another side of corresponding sides are JB~YQ. What's the proportion for JB~YQ?

Best ResponseYou've already chosen the best response.0YQ corresponds to BJ \(\dfrac{YQ}{BJ} = \dfrac{QS}{BD}\) \(\dfrac{YQ}{60} = \dfrac{72}{45}\) \(\dfrac{YQ}{60} = \dfrac{8}{5}\) \(5(YQ) = 8 \times 60\) \(YQ = 96\)
