Answer:
So if you're having difficulty visualizing the differences, you can rewrite them so they all have the same denominator
7/12 = 35/60
1/2 = 30/60
2/3 = 40/60
4/10 = 24/60
1/6 = 10/60
So now it's easier to see how they compare to each other.
10/60, 24/60, 30/60, 35/60, 40/60
And then simplify them or just refer to what they were before
1/6, 4/10, 1/2, 7/12, 2/3
I hope this helps!
We know that According to Law of Sines :

where A - B - C are the Angles of the Three Vertices of the Triangle
a - b - c are the lengths of the Opposite sides of the Angles of the Respective Vertices A - B - C
From the Given Triangle we Can Notice that :



SinC = 0.682

C = 43°
