Answer:
[tex]XY=20\ m[/tex]
Step-by-step explanation:
The picture of the question in the attached figure
we know that
The Intersecting Secant-Tangent Theorem states that: The product of the segments UX and XY on the secant line U
Y equal the square on the tangent line UV.
so
[tex](UX)(XY)=UV^2[/tex]
substitute the given values
[tex](5)(XY)=10^2[/tex]
solve for XY
[tex]XY=100/5\\XY=20\ m[/tex]
