A) \[\frac{xd}{z}\]
B) \[\frac{xz}{d}\]
C) \[\frac{zd}{x}\]
D) \[xzd\]
Correct Answer: C
Solution :
\[\Delta CAB\tilde{\ }\Delta CLO\] |
\[\therefore \,\,\,\,\,\,\,\,\,\,\frac{CA}{CL}=\frac{AB}{LO}\] |
\[\Rightarrow \,\,\,\,\,\,\,\,\,\,\frac{z}{a}=\frac{x}{d}\,\,\,\,\,\,\,\,\,\Rightarrow \,\,\,\,a=\frac{zd}{x}\] |
So, option [c] is correct. |
