Answer:
is there suppose to be a picture
Step-by-step explanation:
Given :
C, D, and E are col-linear, CE = 15.8 centimetres, and DE= 3.5 centimetres.
To Find :
Two possible lengths for CD.
Solution :
Their are two cases :
1)
When D is in between C and E .
. . .
C D E
Here, CD = CE - DE
CD = 15.8 - 3.5 cm
CD = 12.3 cm
2)
When E is in between D and C.
. . .
D E C
Here, CD = CE + DE
CD = 15.8 + 3.5 cm
CD = 19.3 cm
Hence, this is the required solution.
Answer:
3 friends are older than the average.
Step-by-step explanation:
First find the mean. The mean can be found adding all the numbers in the set together and dividing by the amount of numbers in the giving set:
(25 + 36 + 33 + 36 + 30)/5 = (160)/5 = 32
The average age is 32. There are 3 friends that are older than the average (33 , 36 , 36, respectfully).

Calm Down this is a nasty proof
CB is parallel to ED (Given)
CB is congruent to ED (Given)
Angle CBF is congruent to Angle EDF (Vertical Angles)
Angle DEF is congruent to Angle BCF (Alternate Interior Angles)
Angle EDF is congruent to Angle CBF (Alternate Interior Angles)
Therefore we now have enough information to solve. We have a side angle side triangle here so.....
Triangle CBF is congruent to Triangle EDF because of the Side Angle Side Theorem.
Good Luck and Your Welcome
