Option (2)

Step-by-step explanation:

From the given circle graph attached,

Sum of central angles formed by each sector at the center of the circle = 360°

length of the arc of each segment = 360° × percentage area of each sector

Length of arc BC = measure of angle BFC

                            = 360° × 39%

                            = 360 ×

                            = 140.4°

Therefore, Option (2) will be the correct option.

answer: two angles are called supplementary if they add up to 180°. example: the two angles (140° and 40°) are supplementary because they add up to 180°.
