2193 x 10(little 37) over 79
or
≈2.77595 x 10(little 38)
The correct answer to this question is 240
From the image i've seen, the RDC has an angle of 120. So the major arc DC (that passes A and B) has an angle of 240.
So this makes that the measure of the angle of DAC is 240 because of the angle formed by RDC which is 120.
1 whole and 1/3 is the answer
