Answer:
cos B = 9/41
tan B = 40/9
sin B = 40/41
Step-by-step explanation:
There is no picture, so I am making a few assumptions.
I am assuming that angle C is the right angle and is opposite 41.
I am also assuming that angle B is formed by the sides that measure 9 and 41. The hypotenuse is 41.
For angle B, the adjacent leg is 9, and the opposite leg is 40.
cos B = adj/hyp = 9/41
tan B = opp/adj = 40/9
sin B = opp/hyp = 40/41
