A) \[b\tan \alpha \cdot \cot \beta \]
B) \[b(\cot \alpha )\cdot (\tan \beta )\]
C) \[b\tan \alpha \cdot tan\beta \]
D) \[b\cos \alpha \cdot \cot \beta \]
Correct Answer: A
Solution :
\[\tan \alpha =\frac{h}{x},\tan \beta =\frac{b}{x}\] \[\frac{\tan \alpha }{\tan \beta }=\frac{h}{b}\] \[\Rightarrow \,h=b\tan \alpha \cdot \cot \beta \]You need to login to perform this action.
