Answer: Externally tangent.
- A Externally tangent
- B Internally tangent
- C Intersecting at two points
- D Non-intersecting
Correct answer: A. Externally tangent
Explanation: Distance between centres d=√(5²+0²)=5. Sum of radii r₁+r₂=3+2=5. Since d=r₁+r₂ exactly, the circles touch at exactly one external point. Ans: Externally tangent.
The slope of a line is the ratio of vertical change (rise) to horizontal change (run) between any two points on it - equivalently, the tangent of the angle θ the line makes with the positive x-axis.
