Step-by-step explanation:

If   and , then we can use the Pythagorean identity to find and .

Since A is in quadrant I,

Also;

Since A is in quadrant I,

This implies that;

This implies that;

But;

Simplify;

the answer is thin because within context, the stanza concludes the and frail tone the people have toward each other, and the fact that it would be thin, makes the most sense compared to "pliable" or "not hard or firm to the touch". hope this , good luck.
