Find the length of each side of each triangle. if the corresponding sides are proportional, the two triangles are similar.
use the distance formula:
DE=√{[-3-(-1)]²+(-1-3)²}=√20=2√5
EF=√36=6
DF=√32=4√2

DG=√45=3√5
GH=√81=9
DH=√72=6√2

DE/DG=2/3
EF/GH=6/9=2/3
DF/DH=4/6=2/3
DE/DG=EF/GH=DF/DH=2/3

the corresponding sides are proportional, so the two triangles are similar.

Which choice provides the best evidence for the
vodka [1.7K]

Correct option is B, Lines 39-42 ("Normally . . . community")

The "matter of urgency," as Akira explains in lines 39–42, is that he has "an opportunity to go to America, as dentist for Seattle's Japanese community." Chie's response to Akira's marriage proposal is necessary for him to determine whether or not to take the position in Seattle.

The answers to the previous question are not well supported by the evidence in Choices A, C, and D. Choice A is wrong since Akira apologizes for disturbing Chie's peaceful evening in line 39. Lines 58–59 discuss the gravity of Akira's demand, not its immediacy, hence option C is incorrect.

Line 73 merely demonstrates that Akira's suggestion "startled" Chie, not why his request is time-sensitive, hence option D is incorrect.

Here's another question with an answer similar to this Chie and Akira:

How long dose it take to travel 5km at an average speed of 8 m/s? Give your answers in minutes and seconds
eduard

Answer:

625 seconds and 10 minutes

Step-by-step explanation:

distancs=S=5km=5000m

average speed=v=8m/s

time taken=t=?

as we know that

average speed=\frac{distance covered}{time taken}

average speed×time taken=distance covered

here we have to find the time taken

time taken=\frac{distance covered}{average speed}

time taken=\frac{5000m}{8m/s}

time taken=625seconds

now we convert seconds into minutes

\frac{625}{60}

10 minutes
