C. 18 m
D. 20 m
E. 35 m
A. 6 m
B. 16 m
C. 18 m
D. 20 m
E. 35 m
Intersecting secants theorem, i.e., \((AO) \times (OB) = (OD) \times (OC)\)
\((7+5) \times 5=3 \times (OC)\)
\(\implies 4\times 5 = OC\)
\(\implies OC = 20\)
Ans D
\((7+5) \times 5=3 \times (OC)\)
\(\implies 4\times 5 = OC\)
\(\implies OC = 20\)
Ans D
