Answer:
x = 5 units.
Step-by-step explanation:
We use the theorem which states that the lengths of 2 tangents to a circle from one point outside of the circle are equal.
Therefore, as you see from the diagram, the lengths of the 2 tangents containing the 2 parts of the line x must be equal to 2 and 3 units.
So x = 2 + 3 = 5 units (answer).
