the answer on e2020 is

10

4/5

3/5

4/3

step-by-step explanation:

the answer would be c:   ax + b = ax + c

step-by-step explanation:

what

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
