Question
Two chords PQ and RS intersect each other at point ‘A’
inside the circle. If PQ = 5 cm, RA = 3.6 cm and AQ = 1.8 cm, find the length of RS.Solution
PA = 5 – 1.8 = 3.2 cm
Since, PQ and RS are two chords and intersect each other at point ‘A’.
So, PA × AQ = RA × AS
Or, 3.2 × 1.8 = 3.6 × AS
So, AS = 1.6 cm
And, RS = RA + AS = 3.6 + 1.6 = 5.2 cm
