Let's solve the geometry problem step-by-step.
1. Understanding the problem:
We have a circle with center O. Points C, F, and S are on the circumference of the circle. We are given that angle \(\angle C = 49^\circ\), and we need to find the measure of angle g, which is \(\angle FOS\).
2. Key concepts:
* The angle subtended by an arc at the center of a circle is twice the angle subtended by it at any point on the remaining part of the circle.
* Inscribed angle theorem.
3. Applying the concepts:
According to the inscribed angle theorem, the angle \(\angle COS\) (inscribed angle) is half the angle \(\angle FOS\) (central angle) that subtends the same arc.
$$ \angle FOS = 2 \times \angle FCS $$
Since \(\angle FCS = 49^\circ\), we have:
$$ \angle FOS = 2 \times 49^\circ $$
$$ \angle FOS = 98^\circ $$
Therefore, the value of angle g (\(\angle FOS\)) is 98 degrees.
Answer: 98°
