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.
Answer:
i hate thsi coordinate chapter its very difficult chapter u know
Perimeter = x + 5x - 2 + 7x - 4
= 13x - 6 meters answer
30° the angle is ro small to be 90° to small to be 60° and to small to be 120°
