PLEASE MARK ME AS. BRAINLIST
given op = 17 cm and or = oq=10cm
since ⊥ from the center to chord bisects the chord
mq=6cm
in triangle omq...mq=6 cm ,oq= 10cm
by pythagoras theorem
om=√(100-36)
om=8
in triangle omp...om=8cm ,op=17 cm
by pythagoras theorem
pm=√(289-64)
pm=15cm
∴pq=pm-qm
=(15 - 6)cm
⇒9 cm ..ans
