The circle is an illustration of tangent and secant lines, and the length of FE in the circle is 9.3 units
<h3>How to determine the length FE?</h3>
The lengths are given as:
- DE = 12 units
- CD = 16 units
Start calculating the length DF using:
DE * DF = CD²
So, we have:
12 * DF = 16²
Evaluate the exponent
12 * DF = 256
Divide both sides by 12
DF = 21.3
The length FE is then calculated using:
DF = FE + DE
Substitute DE = 12 and DF = 21.3
21.3 = FE + 12
Subtract 12 from both sides
FE = 21.3 - 12
Evaluate the difference
FE = 9.3
Hence, the length of FE in the circle is 9.3 units
