Find all six trigonometric functions of a in triangle ABC

Question

triangle ABC is a right triangle

CA=12

BC=5

Answer 1

Assuming BC and CA are legs of the right triangle, then the hypotenuse AB = 13 (By the Pythagorean Theorem).

Sin B = CA/AB = 12/13

Cos B = BC/AB = 5/13

Tan B = CA/BC = 12/5

Cot B = 1/Tan B = 5/12

Csc B = 1/Sin B = 13/12

Sec B = 1/Cos B = 13/5
