DF = 8
FE = 2
======
Find BF
By similar triangles
FC/FE = DF/FC
FC^2 = 8*2
FC = sqrt(16)
FC = 4
Find AC
First write it like this.
240/x = 80/100
240/x means 240 over the number we are looking for.
80/100 means 80% over 100% which is the number missing.
100(240) / 80 = x
x = 24000/80
x = 300
C i think i cant see it very well
Answer:
the last one
Step-by-step explanation:
12+(16/4+2)2
