Answer» $Here, two \:chords \:AB \: and \:CD ,\: when$ $produced, \: meet \:at \:a \:point \: F.$ $\therefore FB \times FA = FC \times FD$ $\implies ( FA + AB) \times FA = ( FD + DC )\times FD$ $\implies ( 3 + 5 )\times 3 = ( 4 + DC ) \times 4$ $\implies 8 \times 3 = ( 4 + DC ) \times 4$ $\implies \times {8 \times 3 }{4} = 4 + DC$ $\implies 4 + DC = 6$ $\implies DC = 6 - 4$ $\implies DC = 2$ •••♪
