Answer:
No, the triangles are not similar
Step-by-step explanation:
The (reduced) side length ratios, shortest to longest, are ...
12 : 18 : 20 = 6 : 9 : 10
and
5 : 12 : 13
These are not the same, so the triangles are not similar.
-6 degrees F
We start with -8F as the temperature. It fell 10 degrees to 2F, then fell 8 degrees to -6F.
36 3/4
12 1/4 + 12 1/4 + 12 1/4 = 36 3/4 :)
