cos 𝜽 = adj / hyp

cos 𝜽 = 5/13

adj = 5

hyp = 13

Like a right triangle

adj² + opp² = hyp²

5² + opp² = 13²

opp² = 169 - 25 = 144

opp = 12

Therefor

adj = 5

opp = 12

hyp = 13

-------------------------

sin 𝜽 = opp/hyp = 12/13

tan 𝜽 = opp/adj = 12/5

sec 𝜽 = hyp/adj = 13/5

csc 𝜽 = hyp/opp = 13/12

cot 𝜽 = adj/opp = 5/12
