Answer:

∠DFE ≅ ∠DFG

Step-by-step explanation:

we know that

Triangles are congruent by SAS, if any pair of corresponding sides and their included angles are equal in both triangles

In this problem we have that

The pair of corresponding sides that are equal are

EF=GF and DF (is the same side for both triangles)

The included angle are ∠DFE and ∠DFG

therefore

The additional information needed to prove that triangles DEF and DGF are congruent by SAS is that angles ∠DFE and ∠DFG are equal

∠DFE ≅ ∠DFG

Answer:12,376

Step-by-step explanation:

Given

Connie has 17 Pairs of jeans

She has to choose 6 pairs out of 17

We know, no of ways to pick r items out of n items is $^nC_r$

$\therefore \text{No of ways is =}^{17}C_6\\\\\Rightarrow \dfrac{17!}{(17-6)!6!}=12,376\ \text{ways}$

Anybody knows the answer real quick

eduard

Answer:

I think it's 3

Step-by-step explanation:

To calculate the gradient equals to

y(1)-y(2)

-----------

x(1)-x(2)

So - 5 - 1 = - 6

6 - 2 = 4

-6 - 3

--- = ----- x

4 2

And the first y intercept is 1 so I guess it's 3.

Just for refernece, not sure if I'm correct. Sry
