Answer:
-27
Step-by-step explanation:

-z = 80
You cannot submit an equation with a negative letter ( -z ) so we have to cancel the negative.
To cancel negatives in the equation, we multiply both sides by -1.
-z * -1 = 80 * -1
z = -80
Answer: z = -80
B because 1 * 10^5 is equal to 100,000 as it moves 5 digits to the left (5 zeros)
Answer:
605π/18
Step-by-step explanation:
The answer is this cause I have brains.
Since CB || ED and CB = ED,
by the alternate interior angles theorem,
mE = mC, and mD = mB.
with CB = ED, we can conclude that CBF = EDF, by SAS congruent theorem.
