Question
In a circle, two chords AB & CD are produced at P which is outside the circle . If PA= 12 cm, AB= 10 cm , PC = 2 cm then find
In a circle, two chords AB & CD are produced at P which is outside the circle . If PA= 12 cm, AB= 10 cm , PC = 2 cm then find
CD.
We know that when AB & CD two chords intersect at point P, PA `xx` PB = PC `xx` PD So 12 `xx` (12 + 10) = 2 `xx` (2 + CD) 264 = 2 `xx` (2 + CD) 132 = 2 + CD CD = 130 cmMore Circle Questions
