=======================================
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.
Hi!
<h3>To divide a fraction, you multiply by the reciprocal of the second fraction.
</h3><h3>First, convert the mixed numbers to fractions, by multiplying the denominator by the whole number and adding that to the numerator. </h3>

Answer:
the second option from the top is correct. (the one with the dot on -4)
Step-by-step explanation:
d/-2 + 5 = 7
d/-2 = 7 - 5
d/-2 = 2
d = 2 * -2
d = -4
