?:?:?:180
by using cross multiplication 3×180÷15=36
the measure of the smallest angle is 36°
Try dividing both sides by 2.
Hope i helped :)
(It's kinda cool, because by dividing both sides by 2 we get !<3u :)

=======================================
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.
