2. Point M is the midpoint of seg AB, If AB = 8 then find the length of A
3. Point P is the midpoint of seg CD. If CP = 2.5, find I(CD).​

Answer 1

Answer:

Correct option is

C

seg BE and seg AD

Point A B C D E

Co-ordinates −3 5 2 −7 3

DA=−3−(−7)=4,DC=2−(−7)=3

DB=5−(−7)=12,DE=9−(−7)=3+7=16

AC=2−(−3)=5,AB=5−(−3)=8

AE=3−(−3)=12,

CB=5−2=3,CE=9−2=7

BE=9−5=4

seg DA=BE=4

seg DB=AE=12

Option C seg BE and seg AD
