Answers:
- sin(G) = 3/5
- cos(G) = 4/5
- tan(G) = 3/4
- csc(G) = 5/3
- sec(G) = 5/4
- cot(G) = 4/3
==============================================
Explanation:
For a right triangle, the sine of a reference angle is equal to the opposite over hypotenuse.
sin(angle) = opposite/hypotenuse
cosine involves adjacent over hypotenuse
cos(angle) = adjacent/hypotenuse
tangent involves opposite over adjacent
tan(angle) = opposite/hypotenuse
-----------------
In short, we have this list so far
- sin(angle) = opposite/hypotenuse
- cos(angle) = adjacent/hypotenuse
- tan(angle) = opposite/hypotenuse
The other three trig functions are reciprocals of these first three. Cosecant is the reciprocal of sine, secant is the reciprocal of cosine, and cotangent is the reciprocal of tangent.
Meaning, the other three trig ratios are
- csc(angle) = hypotenuse/opposite
- sec(angle) = hypotenuse/adjacent
- cot(angle) = adjacent/opposite
--------------------
So,
- sin(G) = opposite/hypotenuse = FH/FG = 24/40 = 3/5
- cos(G) = adjacent/hypotenuse = GH/FG = 32/40 = 4/5
- tan(G) = opposite/adjacent = FH/GH = 24/32 = 3/4
and
- csc(G) = hypotenuse/opposite = FG/FH = 40/24 = 5/3
- sec(G) = hypotenuse/adjacent = FG/GH = 40/32 = 5/4
- cot(G) = adjacent/opposite = GH/FH = 32/24 = 4/3

Answer:
about 145.3 mg
Step-by-step explanation:
If half breaks down in the hour, then half remains. That is, each hour the amount remaining is multiplied by 1/2. The remainder after 6 hours is ...
(9300 mg)(1/2)^6 = 145.3125 gm
About 145.3 mg will be left after 6 hours.
