Answer:
x=3.75

Explanation:

For this exercise you need to apply the Intersecting Chords Theorem.

In this case, based on that Theorem, you can write the following equation:


CE*DE=AE*BE

You can identify in the picture that:


CE=x\\\\DE=8\\\\AE=6\\\\BE=5

Now, knowing those values, the next step is to substitute them into the equation:


CE*DE=AE*BE\\\\x*8=6*5

Finally, you need to solve for "x" in order to find its value. You get that this is:


8x=30\\\\x=(30)/(8)\\\\x=3.75
