The angle between the curves \(y^2=4 x+4\) and \(y^2=36(9-x)\) is
- A \(30^{\circ}\)
- B \(45^{\circ}\)
- C \(60^{\circ}\)
- D \(90^{\circ}\)
Answer & Solution
Correct Answer
(D) \(90^{\circ}\)
Step-by-step Solution
Detailed explanation
Given curves are \[ y^2=4 x+4 \text { and } y^2=36(9-x) \] On solving, we get the points \((8,6)\) and \((8,-6)\). On differentiating Eq. (i), we get…
