AP EAMCET · Maths · Circle
Two circles each of radius units touch each other at and is their common tangent. The equation of that circle among the two given circles, such that some portion of it lies in every quadrant is
- A
- B
- C
- D
Answer & Solution
Correct Answer
(C)
Step-by-step Solution
Detailed explanation
The figure below represents the two circles with the common tangent. The slope of the common tangent, m=-43 The slope of the line perpendicular to tangent is, m'=tanθ=34 Therefore, sinθ=35,cosθ=45 Now, …
