Answer:
C
Step-by-step explanation:
We are given that
DCB and CDA are supplementary.
We have to identify the parallel segments if DCB and CDA are supplementary.
Supplementary angles: If the angles are supplementary then the sum of two angles is 180 degrees.
Therefore,
Therefore, angle DCB and angle CDA are interior angles .
Because CA is a transversal line and sum of interior angles is 180 degrees.
When the sum of interior angles formed between two lines and on same side of transversal line is 180 degrees. Then the lines are parallel.
Therefore, angle DCB and angle CDA are formed between line AD and BC.
Hence, AD is parallel to BC.
Option C is correct.

Step-by-step explanation:
#42.
14n - 32 = 22
add 32 to both sides
14n - 32 + 32 = 22 + 32
simplify
14n = 54
divide both sides by 14
14n/14 = 54/14
simplify
n = 3 12/14
n = 3 6/7 or n = 3.857
Answer:
Mean= 31
Step-by-step explanation:
To find the mean you need to add all the number together and then divide by how many ever numbers there are.
In this case
25 + 25 + 30 + 35 + 40=155
There are 5 numbers so you would divide by 5
155/5
=31
