Answer:

DC = 3

Step-by-step explanation:

BD = DC                             [Two tangents drawn from an external point of

or, -2x + 5 = 3x                    the circle are equal in length.]

or, 5x = 5

or, x = 1

Now,

DC = 3x = 3(1) = 3

Answer:

3

Step-by-step explanation:

Since the lines are tangents originating from the same points and join to the same axis of circle A,they are equal.

  • BD = DC

Equation

5-2x = 3x

  • 5x = 5
  • x = 1

So DC = 3*1 = 3
