The measure of arc ECF in circle G is 98°. The correct option is the second option 98°
<h3>Circle Geometry </h3>
From the question, we are to determine the measure of arc ECF
By using the one of the circle theorems
The angle subtended by an arc of a circle is twice the angle it subtends anywhere on the circle's circumference
In the given diagram,
∠F = 1/2 ×104°
∠F = 52°
∠D + ∠E + ∠F = 180° (<em>Sum of angles in a triangle</em>)
∠D + 79° + 52° = 180°
∠D = 180° - 79° - 52°
∠D = 49°
m arc ECF = 2 × m ∠D
m arc ECF = 2 × 49°
m arc ECF = 98°
Hence, the measure of arc ECF in circle G is 98°. The correct option is the second option 98°
