Which of the following statements is true about the triangles below?
a. δabc = δdef by ssa
b. δabc = δdef by aas
c. δabc = δdef by sas
d. δabc = δdef by asa

The correct option is c.

Step-by-step explanation:

From the given diagram we have two triangles.

In triangle ABC and DEF,

                  (Given)

                  (Given)

                  (Given)

According to the SAS property of congruent triangles, two triangles are congruent if two sides and included angle is same.

By SAS property of congruent triangles, we get

Therefore the correct option is c.

according to egenuity the answer is

step-by-step explanation:

d. 344.22

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.

you,
