Complete the pairs of corresponding parts if △ABD ≅ △EFC. ∠A =

∠ FCE
∠ FEC
∠ EFC

We conclude that:

∠A = ∠ FEC

Step-by-step explanation:

Given

△ABD ≅ △EFC

To determine:

∠A =

As

△ABD ≅ △EFC

So the triangles △ABD and △EFC are congruent to each other.

Please check the attached graph.

From the graph, it is clear that ∠A is correspondent to ∠E.

∠A = ∠E

From the attached figure, it is clear that:

∠F can also be denoted by ∠ FEC

as

∠A = ∠E

so

∠A = ∠ FEC

Therefore, we conclude that:

∠A = ∠ FEC

oof cheaters cheat because they’re lazy that’s why i cheat xd

step-by-step explanation:

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
