Concept:

From the same external point, the tangent segments to a circle

are equal.

Calculation:

F1 S.G 30-01-2020 savita D2

Given, AB = 10 cm, AC = 8.6 cm and BC = 6.4 cm

Let BE = x cm and CF = y cm

As we know,

BE = BD [tangents]

DC = CF [tangents]

AE = AF [tangents]

AB + BE = AC + CF

⇒ 10 + x = 8.6 + y

⇒ x – y = 8.6 – 10

⇒ x – y = - 1.4         ----(1)

BD + DC = 6.4

⇒ x + y = 6.4         ----(2)

From equation (1) and equation (2)

⇒ x = 2.5

∴  BE = 2.5 cm
