If ARST = XYZ, which statement must be true? R
S
X
Y
A. ZS, ZZ
0
B. ZR: ZX
C. RSST
OD. ST = XZ
SUBMIT

The answer is B.

Step-by-step explanation:

That's because in A. angle S and angle Z aren't corresponding in the congruence of RST and XYZ.  

In C. line RS and line ST can' be proven to be congruent because they arent a part of the what we know which is RST is congruent to XYZ. It says nothing about RS being congruent to ST.

And D. has the same problem as A. with the line ST and line XZ not corresponding the what we know. If it had said ST is congruent to YZ, or that RT is congruent to XZ then it would be true. Because RST is congruent to XYZ. And R corresponds to X, S corresponds to Y, and T corresponds to Z.

So B. would be the answer because R and X correspond to one another because it's written as RST ans XYZ and both R and X are the first letters represented in both triangles.

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
