Practice 1: Use the diagram drawn from to find the indicated angle measures. "name": "Q.2. For a point \(D\) on \(BC\) that divides it in the ratio \(m:n,\) the theorem states that, \((m + n) \cot \theta = m \cot \alpha n \cot \beta \), \((m + n) \cot \theta = m \cot B n \cot C\), Given:\(\frac{{BD}}{{DC}} = \frac{m}{n}\) and \(\angle ADC = \theta \), \(\angle ADB = {180^{\rm{o}}} \theta \), So, \(\angle ABD = \theta \alpha = B,\) and \(C = {180^{\rm{o}}} (\theta + \beta )\), In \(\Delta ABD,\frac{{BD}}{{ \sin \alpha }} = \frac{{AD}}{{ \sin (\theta \alpha )}}\), In \(\Delta ADC,\frac{{DC}}{{ \sin \beta }} = \frac{{AD}}{{ \sin (\theta + \beta )}}\), \(\frac{{BD}}{{DC}}\frac{{ \sin \beta }}{{ \sin \alpha }} = \frac{{ \sin (\theta + \beta )}}{{ \sin (\theta \alpha )}}\), \( \Rightarrow \frac{{m \sin \beta }}{{n \sin \alpha }} = \frac{{ \sin (\theta + \beta )}}{{ \sin (\theta \alpha )}}\), \(\frac{{m \sin \beta }}{{n \sin \alpha }} = \frac{{ \sin \theta \cos \beta + \cos \theta \sin \beta }}{{ \sin \theta \cos \alpha \cos \theta \sin \alpha }}\), \(m \sin \beta ( \sin \theta \cos \alpha \cos \theta \sin \alpha ) = n \sin \alpha ( \sin \theta \cos \beta + \cos \theta \sin \beta )\), \(m \cot \alpha m \cot \theta = n \cot \beta + n \cot \theta \).
