Answer:
13
[tex]FC + CB = \frac{DC}{2} +\frac{AB}{2}[/tex]
Step-by-step explanation:
Line CB is half of Line AB, which the questions says line AB is the length of 20. 20/2 = 10.
Line CB is 10.
The question also says that point F is the midpoint of line DC. Line DE is 12. Line DC is half of 12, which means its 6. F is the midpoint of Line DC which means it's also half of Line DC, which is 3.
Line FC is 3.
The question asks you to find the value of Line FC PLUS Line CB. So 10 + 3 = 13.
Your answer is 13.
Answer:
13
Step-by-step explanation:
AB and DE split each other equally in half so
if AB = 20 then CB = 10
and if DE = 12 then DC = 6
meaning that FC = 3
3+10=13
