51. In given figure, if AX = 5 cm, XD= 7 cm, CX= 10 cm, find BX


(A) 3 cm                               (B) 3.4 cm
(C) 4 cm                                (D)4.5 cm

Dear student,

We know that,If a point P in the interior of a circle, pass two ines through P that intersect the circle in point A and D and respecively B and C thenAP×DP=BP×CP

Using the same in the given question
Similarly we have,AX×XD=BX×XC5×7=BX×10BX=3510BX=3.5 cmThus option B is correct

Regards
