Question

Solve for x.
A. 2
B. 1
C. 3
D. 5

Answer 1

x = 3

Explanation:

The tangents drawn from a point outside a circle are of equal length.

2x + 1 + 9 = x + 3 + 10

2x + 10 = x + 13

Now, subtract 10 from both sides,

2x = x + 13 - 10

2x = x + 3

Subtract 'x' from both the sides,

2x - x = 3

`\boxed{\bf x = 3}`
