TS EAMCET · Maths · Pair of Lines
If the slope of one of the lines represented by is , then the angle between the pair of lines is
- A
- B
- C
- D
Answer & Solution
Correct Answer
(D)
Step-by-step Solution
Detailed explanation
Given, The slope of one of the lines represented by 5x2+403xy+ky2=0 is 3 Now comparing with ax2+2hxy+by2=0 we get, m1+m2=-2hb=-403×k & m1m2=ab=5k, Now taking m1=3 we get, 3+m2=-403×k & 3m2=5k ⇒3+53k=-403×k …
