You can put this solution on YOUR website!

AC=12 and BC=5
=> AB=sqrt%285%5E2%2B12%5E2%29=13

the sine of angle A (opposite divided by hypotenuse),
the cosine (adjacent divided by hypotenuse) and
the tan or tangent (opposite divided by adjacent).
cos%28A%29=12%2F13 ->correct
sin%28B%29=12%2F13->correct
sin%28A%29=5%2F13+->correct
these are incorrect:
tan%28B%29=5%2F12....correct would be ->12%2F5
tan%28A%29=12%2F13 ...correct would be->5%2F12
