Answer:
(C)[tex]47.5^\circ[/tex]
Step-by-step explanation:
In the circle, the measure of arc ED is the measure of an angle subtended by arc ED at the centre.
Angle EFD on the other hand is an angle subtended by arc ED on the circumference.
We have a circle's theorem that states:
The angle subtended by the arc at the centre is twice the angle subtended by the same arc at the circumference, therefore:
[tex]m\angle ED=2 \times m\angle EFD\\95^\circ=2 \times m\angle EFD\\m\angle EFD=95 \div 2\\m\angle EFD=47.5^\circ[/tex]
