Find the length of arc ac, cb=60degrees, ab=12ft(diameter)

Length of arc = radius × angle
Radius= diameter ÷2 =12÷2=6
And put in ur values to obtain the answer

Since we know that arc ab is 180 because ab is a diameter, we know that arc ac + another arc must be equal to 180 in order for the circle to have 360 degrees. Thankfully they gave us that the other arc is 60 degrees, so to find arc ac subtract 60 from 180.

Final arc ac = 120

(-14+3/2b) - (1+8/2b) = -5 -5/2b(-10+b) + (7b-5) = 8b-15(7/2b-3) - (8+6b) = -5/2b-11(5+2b) + (2b+3/2) = 4b+ 13/2
