Line segments AD and BE intersect at C, and triangles ABC and DEC are formed. They have the following characteristics: ∠ACB and ∠DCE are vertical angles

∠B ≅ ∠E

BC ≅ EC

Which congruence theorem can be used to prove △ABC ≅ △DEC?

HL
ASA
SSS
SAS

answer:

a=9

step-by-step explanation: lmk if you need a explanation

2+2 obliviously is 4.

graph #4 (last graph) depict the function   f(x)= -m(x-d)^1/5 i

step-by-step explanation:

we know that

m=slope

but in this function slope is -m that means slope is decreasing and it is decreasing by 1/5 points down the x-axis.

which is shown in graph four

a decreasing slope down x-axis by 1/5 points.

hence 4th graph is the right option for this.
