Answer 1

In this question, we have to order the sides of the triangle from the longest side to the shortest.

The angle-side theorem states that, in a triangle, the side opposite to the larger angle is the longest side. Similarly, the side opposite the shortest side is the shortest.

Now, if we have a look at the triangle and sort it by angles and opposite sides:

Largest angle = E = 99

hence, the longest side would be opposite to E = DF

Second large-angle = F = 42

hence, the second long side would be opposite to F = ED

Smallest angle = D = 39

So, the smallest side would be opposite to D = EF
