sin B = b/c
cos B = a/c

Explanation:

the formula for sin is sin(an angle) = #(opposite)/(hypotenuse)#
so since c is the side length of the hypotenuse and b is the side opposite of Angle B then the #sin B = b/c#

the formula for cos is cos(an angle) = #(adjacent)/(hypotenuse)#
since a is the side adjacent to Angle B and c is the hypotenuse the #cos B = a/c#

#sin(theta)= o/h# soh
#cos(theta) = a/h# cah
#tan(theta) = o/a# toa
