1. We don't know the meaning of "{There is a box image here}".
If you're dealing with congruent figures, match the corresponding letters in the name of the figure:
.. E F G H
.. Q R S T
If you're concerned with QT (1st and 4th letters), you need to look at EH (1st and 4th letters).
If EFGH ≅ QRST, then QT = EH = 6.3.
2. LM = ST = 5.2
the first/upper one
the other point cloud is too compact to leave a clear clue about any slope
In order to find this out, we just needed to find out which one has the same smallest fraction
25 / 35. Divided this by 5 and we will get 5/7 >>> smallest fraction
15/21 . Divided this by 3 and we also will get 5/7 >> smallest fraction
So the answer would be : B. 15/21
hope this helps
