Mathematics · Circle
Two tangents are drawn from a point P to the circle x2 + y2 - 2x - 4y + 4 = 0, such that the angle between these tangents is tan-1(12/5), where tan-1(12/5) ∈ (0, π). If the centre of the circle is denoted by C and these tangents touch the circle at points A and B, then the ratio of the areas of ΔPAB and ΔCAB is:
- 12 : 1
- 23 : 1
- 39 : 4✓
- 411 : 4
Correct answer
9 : 4
