The right triangle shown has angles x, y, and z and side lengths a, b, and c. which equation is not true for this triangle?

(You forgot to provide the choices!?!)

A.) Cos Z = b/c

B.) Sin X= c/b

C.) Tan X = b/a

D.) Tan Z = a/b

B is the answer, Sin X = c/b is wong because Sin X= b/c ( sin = opposite/ hypotenuse)

Hope this helps.!

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
