If $$\theta $$ be acute angle and $$\cos \theta = \frac{{15}}{{17}}{\text{,}}$$ then the value of $${\text{cot}}\left( {{{90}^ \circ } - \theta } \right)$$ is?
A. $$\frac{{2\sqrt 8 }}{{15}}$$
B. $$\frac{8}{{15}}$$
C. $$\frac{{\sqrt 2 }}{{17}}$$
D. $$\frac{{8\sqrt 2 }}{{17}}$$
Answer: Option B
Solution(By Examveda Team)
$$\cos \theta = \frac{{15 \to {\text{Base}}}}{{17 \to {\text{Hypo}}}}$$$$\eqalign{ & {\text{Perpendicular = 8}} \cr & \Rightarrow {\text{cot}}\left( {{{90}^ \circ } - \theta } \right) \cr & \Rightarrow {\text{tan}}\theta = \frac{8}{{15}}\left[ {\therefore \tan \theta = \frac{{\text{P}}}{{\text{B}}}} \right] \cr} $$
