△def is similar to △stu. write a proportion that contains st and su.

The proportionality statement is  

Step-by-step explanation:

Given that ΔDEF is similar to ΔSTU.

We have to write the proportionality that contains the sides ST and SU.

As we know the statement of proportionality, for the two shapes to be similar, the sides must be in proportion i.e

we have to write the proportionality statement which contains ST and SU

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
