#SinA=2/11#
#CosA=(3sqrt(13))/11#
#TanA=(6sqrt(13))/117#
#CscA=11/2#
#SecA=(33sqrt(13))/117#
#CotA=(3sqrt(13))/2#

Explanation:

Trigonometric Ratios
Sin= Opposite/Hypotenuse
Cos= Adjacent/Hypotenuse
Tan= Opposite/Adjacent
Csc= 1/sin
Sec=1/cos
Cot= 1/tan

The side A has to be opposite to angle A when you solve these ratios, and rationalize as needed. I assumed the C was your hypotenuse. I used Pythagorean theorem to solve for side B, #B=sqrt(C^2-A^2)#
