The calculated length of the segment HG is 15 units
How to determine the length of the segment HG
From the question, we have the following parameters that can be used in our computation:
The circle
Where, we have
EF = 18
FG = 12
Using the intersecting secant theorem, we have
18 * 18 = 12 * (12 + GH)
So, we have
12 + GH = 27
Evaluate
GH = 15
Hence, the length of the segment HG is 15 units
Question
