Answer :
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
