Answer:
45 degrees
Step-by-step explanation:
I asked above, but you didn't answer, but I think you mean the measure of arc ADC or angle ADC, not ACD.
The circumference of the circle is 600 cm.
The length of the arc is 75 cm.
First we find what fraction 75 cm is of 600 cm.
(75 cm)/(600 cm) = 0.125
A full circle has a measure of 360 degrees. Since this arc has a length which is 0.125 of the circumference of the full circle, it is also a degree measure which is 0.125 of the degree measure of a full circle.
0.125 * 360 degrees = 45 degrees
