We know that According to Law of Sines :
[tex]\frac{SinA}{a} = \frac{SinB}{b} = \frac{SinC}{c}[/tex]
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 :
[tex]\frac{SinC}{28} = \frac{Sin92}{41}[/tex]
[tex]SinC = \frac{0.999\times28}{41}[/tex]
[tex]SinC = \frac{27.98}{41}[/tex]
SinC = 0.682
[tex]C = \sin^-^1(0.682)[/tex]
C = 43°
