AB is a chord of length 24 cm of a circle with centre O and radius 13 cm. Find the distance of the chord from the centre.
A)5cm
B)6cm
C) \[\angle ABD\]
D)None of these
Correct Answer:
A
Solution :
AB = 24cm and \[{{90}^{o}}\] So, AM = MB =12 cm, OA = 13 cm (given). In\[l||m,\] \[{{130}^{o}}\] (By pythagorus theorem) \[{{50}^{o}}\] \[{{120}^{o}}\] \[\angle A={{80}^{o}}\]
