The measure of arc CD, the portion of Earth from which the signal is visible is 56°.
<h3>How to calculate the angle?</h3>
From the information given, we are told that The satellite can only send a signal over the part of Earth that is visible to the satellite.
Let the angle be a. Therefore,
Cos a = 4000/(4000 + 2800)
Cos a= 4000/6800
Cos a = 0.5882
Cos a= 56°
