Summary of Equations

If a length is desired :

OPP = HYP x Sin(ANG)

OPP = ADJ x Tan(ANG)

HYP = OPP/Sin(ANG)

HYP = ADJ /Cos(ANG)

ADJ = HYP x Cos(ANG)

ADJ = OPP/Tan(ANG)

If an angle is desired :

ANG = Sin^-1(OPP/HYP)
ANG = Cos^-1(ADJ/HYP)
ANG = Tan^-1(OPP/ADJ)

Cosine Rule

ANG = Cos^-1((ADJ1² + ADJ2² - OPP²)/(2 x ADJ1 x ADJ2))
