Please help!! The options for both of these is right here!

Card A:
16
6
90
9

Card B: Card B *
QR
TU
RS
ST

Given:

Triangle ABC is similar to triangle EFG.

Pentagon ABCDE is similar to pentagon QRSTU.

To find:

The length of segment FG.

The missing value in .

Solution:

In card A,

AC = 15 in.

BC = 9 in.

EG = 10 in.

Triangle ABC is similar to triangle EFG. So, the corresponding sides are proportional.

Putting the values, we get

Divide both sides by 5.

Therefore, the length of segment FG is 6 in.

In card B, pentagon ABCDE is similar to pentagon QRSTU.

The corresponding sides of similar figure are proportional. So,

Now,

It can be written as

Therefore, the missing side is ST.

i'm not sure i quite understand, could you provide more information?
