Answer : Sin G = Cos I: Tan G is a reciprocal of Tan I
For < G
HI = opposite
GI = Hypotenus
GH = adjacent
Sin G = opposite / Hypotenus
SinG = HI / GI
Sin G = HI/GI
Cos I = adjacent / hypotenus
Cos I = HI / GI
Therefore, Sin G = Cos I
Tan G = HI / GH
Tan I = GH/HI
Therefore, Tan G is a reciprocal of Tan I
