Question

In a circle with center P, chord AB is drawn of length 13cm, seg PQ ⊥ chord AB, then

find ℓ(QB)

a) 3cm b) 5.5cm c) 4cm d) 6.5cm​

Answer 1

Answer:

l(QB)=6.5 cm

Step-by-step explanation:

Given: P is the centre of the circle. AB is the chord.Length of chord AB is 13 cm. Seg PQ is perpendicular to chord AB.

To Find : l(QB)

Solution: PQ divides chord AB into two parts

i.e.AQ and QB.

QB=1/2×13

l (QB)=6.5 cm

Therefore,the length of QB is 6.5cm
