b=5
B=?

Tan=

Answer 1

`{a}^(2) + {b}^(2) = {c}^(2) \\ {a}^(2) + {5}^(2) = {13}^(2) \\ {a}^(2) + 25 = 169 \\ {a}^(2) = 169 - 25 \\ {a}^(2) = 144 \\ a = 12`

`\sin(B) = (Opposite)/(hypotenuse) = (5)/(13) \\ \\ \\ \cos(B) = (adjacent)/(hypotenuse) = (12)/(13) \\ \\ \\ \tan(B) = (opposite)/(adjacent) = (5)/(12)`
