The measurements of the angles ∠ABD and ∠ACD will be 34° and 34°. Then the correct option is C.
What is a circle?
It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.
The central angle is double the angle at the periphery that was subtended by the same chords.
Then the arc AD is double of angle ∠ABD.
∠ABD = arc AD / 2
∠ABD = 68° / 2
∠ABD = 34°
Similarly, the arc AD is double of angle ∠ACD.
∠ACD = arc AD / 2
∠ACD = 68° / 2
∠ACD = 34°
Thus, the measurements of the angles ∠ABD and ∠ACD will be 34° and 34°.
Then the correct option is C.
