=======================================
Explanation:
Recall that tangent is the ratio of opposite over adjacent
tan(angle) = opposite/adjacent
So for reference angle G, we say,
tan(G) = JH/GJ = 2/1 = 2
We'll treat tan(H) in a similar fashion, but the opposite and adjacent sides swap roles. That means we'll apply the reciprocal to the result above to get 1/2 for tan(H)
-----------
So we have this interesting property where
tan(G)*tan(H) = 2*(1/2) = 1
In general,
tan(A)*tan(B) = 1 if and only if A+B = 90 degrees
-----------
Side note: The side sqrt(5) isn't used at all.
Potatoes: $2.52 / 4.5lbs = $0.56 / lb.
Broccoli: $7.75 / 2.5lbs = $3.1 / lb
Pears: $2.45 / 2.5lbs = $0.98 / lb
