Answer:
AA Similarity Postulate
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent
step 1
Verify the proportion of the corresponding sides

substitute

----> is true
Corresponding sides are proportional
Triangle PQR is similar to Triangle PST
That means
Corresponding angles must be congruent
side QR is parallel side ST
and
----> by corresponding angles
--> by corresponding angles
so
PQR is similar to PST by AA Similarity Postulate

73 • 7 - 5 = 511 - 5 = 506
U can use elimination and multiply all the terms in the top expression to get 3x-3y = -4, or 4x = -4, so x = -1. plug it in to find y if needed
Answer:
volume of box = 312.375 in²
Explanation:
The volume of a rectangular box can be measured as follows:
volume = length* width * height
From the givens we have:
length = 8.5 in
width = 5.25 in
height = 7 in
Substitute with the givens in the above equation to get the volume as follows:
volume = length * width * height
volume = 8.5 * 5.25 * 7
volume = 312.375 in²
Hope this helps :)
