We know that According to Law of Sines :

(SinA)/(a) = (SinB)/(b) = (SinC)/(c)

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)/(28) = (Sin92)/(41)

SinC = (0.999*28)/(41)

SinC = (27.98)/(41)

SinC = 0.682

$C = \sin^-^1(0.682)$

C = 43°
