Ppp(444) + 555 ≥323232
this is your inequality
hope this helps
Mid point b/w (18,-6),(0,0)
X = 0+18/2 = 9
y = 0-6/2 = -3
thus mid point is (9,-3)
C=1.9. this is an estimate.

bearing in mind that, arcs get their angle measurement from the central angle they're in. Thus, the measure of that central angle, is the same measure in degrees of that arcDF.
A.) a is 3 because it's bigger than b
b.) b is 3 because it's less than a and both would equal to 5
c.) x is idk sry it might be 2 1/2 or 3 but idk
