A) Intersect each other at angle of \[45{}^\circ \]
B) Are parallel to each other
C) Are perpendicular to each other
D) None of these
Correct Answer: C
Solution :
[C] \[{{\left. \frac{dy}{dx}=\frac{2y+3x}{2x+5y}\Rightarrow \frac{dy}{dx} \right]}_{({{x}_{1}}-{{y}_{1}})}}=0\] &\[\]\[{{\left. \frac{dy}{dx} \right]}_{({{x}_{2}},{{y}_{2}})}}=\infty \] \[\Rightarrow \]tangents are perpendicularYou need to login to perform this action.
