What is the value of x ??
RideAnS [48]

Answer:

4.2mm

Step-by-step explanation:

This are two similar triangles.

Comparing the two:

8/3 = (7+x)/x

Cross multiplying

8x = 3 (7+x)

8x = 21 + 3x

8x - 3x = 21

5x = 21

Dividing by 5

X = 21/5

X = 4.2mm

-7x+2y=18;6x+6y=0 in elimination form
AlexFokin [52]

Step-by-step explanation:

-7x + 2y = 18

6x + 6y = 0

21x - 6y = - 54

6x + 6y = 0

27x = -54

x = -2

6(-2) + 6y = 0

-12 + 6y = 0

6y = 12

y = 2

Which pair of segments are corresponding parts of the congruent quadrilaterals that are pictured below?
Lunna [17]

Answer:

Segment A B and Segment Z W

Step-by-step explanation:

we know that

If two figures are congruent, then its corresponding sides and its corresponding angles are congruent

In this problem

Sides C D and Y X are congruent,

sides C B and Y Z are congruent,

sides Z W and A B are congruent,

sides A D and X W are congruent

so

ABCD≅WZYX

The corresponding sides are

AB and WZ

BC and ZY

CD and YX

AD and WX

That means

AB ≅ WZ

BC ≅ ZY

CD≅ YX

AD ≅ WX

The corresponding angles are

∠A and ∠W

∠B and ∠Z

∠C and ∠Y

∠D and ∠X

That means

∠A ≅ ∠W

∠B ≅ ∠Z

∠C ≅ ∠Y

∠D ≅ ∠X

therefore

The answer is

Segment A B and Segment Z W

*BEST ANSWER WILL BE MARKED BRAINLIEST*
Gwar [14]
Alright

for a 45-45-90 triangle, if the legs are x then the hytponuse is x√2


so LM=x√2 is right
NM=x

also, tan=oposite side/adjacent side
so that would be LN/MN or MN/LN=x/x=1

so that would be tan(45)=1

so you want to check the 1st one, 3rd one and 5th one

NM=x
LM=x√2
tan(45°)=1 are the answers
