Ответ:
Option (1). 34°
Step-by-step explanation:
From the figure attached, CE and CD are the radii of the circle C.
Central angle CED formed by the intercepted arc DE = 68°
Since measure of an arc = central angle formed by the intercepted arc
Therefore, m∠CED = 68°
Since m∠EFD =
[Central angle of an intercepted arc measure the double of the inscribed angle by the same arc]
Therefore, m∠EFD =![\frac{1}{2}(68)](/tpl/images/0676/0886/1b5b3.png)
= 34°
Therefore, Option (1) 34° will be the answer.
