Answer:
in triangle ACD and BCE
AC = EC
angle ACD = angle ECB ( COMMON ANGLE).
CB = CD
BY side and side criteria
triangle ACD is congruent to triangle BCE
so angle a is congruent to angle E
hence, proved
50=10+.2x so if you solve for x you get x=200. Hope this helps:)
Answer:
s=21
Step-by-step explanation:
given ,
area=441cm^2
length (l)=s
we know,
or,l^2=441cm^2
or,l=√441cm^2
or,l=21cm
They look yo be all functions due to them not intersecting one another
