Answer:
in triangle ACD and BCE
AC = EC

Answer:
a≥0
Step-by-step explanation:
The equation on the left is absolute value so all values plugged in will be positive but on the other side if a negative was plugged in it would still be negative and thus result in a lower sum than the other side. For example:
|-2+5|=-2+5
7=3
this is untrue.
the equation would only be true if the a values were positive.
I do this but I don’t remember how
