Question:
The angle between the lines whose intercepts on the axes are (a,-b) and (b,-a) respectively, is
The angle between the lines whose intercepts on the axes are (a,-b) and (b,-a) respectively, is
Show Hint
Use tanθ=|(m₁-m₂)/(1+m₁m₂)|.
Updated On: Mar 19, 2026
- tan⁻1((a²-b²)/(ab))
- tan⁻1((b²-a²)/(2))
- tan⁻1((b²-a²)/(2ab))
- None of these
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Slopes:
m₁=-(b)/(a), m₂=-(a)/(b)
tanθ=|(m₁-m₂)/(1+m₁m₂)|
=|((a²-b²)/(ab))/(2)|
=(|b²-a²|)/(2ab)
