Answer:
b
Step-by-step explanation:
Answer:
5.5
Step-by-step explanation:
B is the midpoint of AC, D is the midpoint of CE
This means that CE = 1/2 AE
CD = 1/2 ( 11)
CD = 5.5
Step-by-step explanation:
Since the 2 side lines are parallel,

(Note that you can further simplify the equation if you wish to, this is a general equation.)
(Equation formed due to Corresponding angles and Sum of angles on the same straight line)
15.75=5(1+i)^2
3.15=1+i^2
2.15=i^2
i= √2.15 or approximately 1.47
-6(-3)=18, so that is true
-6+(-3)=-6-3=-9 so that is true
-6-(-3)=-6+3=-3 FALSE
-6 ÷ (-2)=2 so that is true
Answer is C
