if Angle=x Adj=y Hyp=?

then Hyp=y/cos(x)

if Angle=x Adj=? Hyp=y

then Adj=y*cos(x)

if Angle=? Adj=x Hyp=y

then Angle=cos^-1*(x/y)

if Angle=x Opp=y Hyp=?

then Hyp=y/sin(x)

if Angle=x Opp=? Hyp=y

then Opp=y*sin(x)

if Angle=? Opp=x Hyp=y

then Angle=sin^-1(x/y)

if Angle=x Opp=y Adj=?

then Adj=y/tan(x)

if Angle=x Opp=? Adj=y

then Opp=y*tan(x)

if Angle=? Opp=x Adj=y

then Angle=tan^-1(x/y)
