A) \[{{45}^{o}}\]
B) \[\theta ={{\tan }^{-1}}(0.25)\]
C) \[\theta ={{\tan }^{-1}}4\]or \[(\theta =76{}^\circ )\]
D) \[{{60}^{o}}\]
Correct Answer: C
Solution :
\[R=4H\cot \theta .\] When \[R=H\] then \[\cot \theta =1/4\]\[\Rightarrow \theta ={{\tan }^{-1}}(4)\]You need to login to perform this action.
