a right triangle ABC has a hypotenuse of Y a short leg of 47.3 and a short leg of X.Angle B =53 degrees, what is x?

Angle A = 37 degrees

The problem here is that we don't know if the "x" side lies across from A or B

If it lies across from A, then

x= 47.3  tan 37

If it lies across from B, then

x = 47.3  tan 53
