Answer:
8
Step-by-step explanation:
This can be solved using intersecting chord theorem. This tells us that when 2 chords intersect inside a circle, the 4 segment it creates, each individual segments' products are equal.
Thus, we can say that the product of 5 and x is equal to the product of 10 and 4. Thus:
[tex]5*x=10*4\\5x=40\\x=\frac{40}{5}\\x=8[/tex]
Hence x = 8 is the correct answer
