Answer:

50

Explanation:

bfa and afe will add up to equal 180 because they are supplementary

20x+2x+70=180

22x+70=180

22x=110

x=5

then you plug in 5 to 2x+70 to get 80

cfe and afe are also complementary so they will add up to equal 180 so angle cfe equals 100

cfd and cfe are the same angles so 100/2=50.

the arc length is the same as the angles so arc length dc is 50
