To find the length of FG, we first need to understand that CH and CF represent the distances from the center C to points H and F on the circumference of the circle. Since both H and F lie on the circumference, CH and CF are both radii of the same circle.
Given:
- CH = 42 m (radius)
- CF = 58 m (not possible since both should be the same radius in a circle)
From this, we can infer there might be an issue with interpreting CF as a radius. The lengths CH and CF do not refer to the same circle since they are different.
Assuming CH and CF represent two different circles with different radii, we can try to work with the given distances:
1. If points D, E, F, and G are points on one circle (for example, radius CH = 42 m), then the distance FG can be calculated using the properties of geometry.
2. The information provided does not explicitly state how FG is related to CH or CF.
Given the choices, and assuming we need to find a reasonable length for FG based on the context where the circle might be divided or if FG is in relation to the given radii indirectly, we could consider common chord length formulas or similar figures based on equal divisions.
Since we are limited by the information, determining the length of FG conclusively based only on the circle properties and not having direct relationships established leads us to make an assumption.
However, if we assume that FG is a segment of a circle with both endpoints equidistant from center C, divided by two equal radii, we can simplify:
- If we take the average of the circles given (42 m and 58 m), it could suggest that length FG possibly represents a reasonable half or related chord length about 40 m.
Thus, based on the provided options and reasoning, the length of FG is likely **40 m**.
