using pathegorean theorm calculate he 3rd side so that you have all 3 sides,
a^2 + 25 = 169
subtract 25 from each side
a = squareroot of 144
a = 12 b =5 c = 13
sin = opp/hyp = 5/13 csc = 1/sin = 1/ 5/13 = 13/5
cos = adj/hyp = 12/13 sec = 1/cos = 1 / 12/13 = 13/12
tan = opp/adj = 5/12 cot = 1/tan = 1/ 5/12 = 12/5
