Options
- A6
- B4
- C3
- D2
Correct answer
C. 3
Step-by-step solution
Given equation of hyperbola is aligned x^2-3 y^2 & =3 x^2 3 - y^2 1 & =1 aligned Here, a^2=3 and b^2=1, a>b . Now, the equation of asymptote of this hyperbola is, aligned y & = b a x y & = 1 3 x aligned Let slope of asymptote (i) is, m₁= 1 3 and slope of asymptote (ii) is, m₂= -1 3 Let be the angle between both asymptote, then = | m₁-m₂ 1+m₁ m₂ |= | 1 / 3 +1 / 3 1-1 / 3 | array cc & = | 2 / 3 2 / 3 |= 3 & = 60^ & = / 3 array
