Precalculus question

1. what is the tangent of angle y?

a. tan y= y/z
b. tan y = x/z
c. tan y = z/y
d. tan y = y/x

By definition you have that the tangent of an angle in a right triangle is given by the quotient between the sine of the angle and the cosine of the angle.
 Since we know how much the sine and the cosine measure (we have the sides of the triangles as data), then the tangent is given by:
 A. tan Y= y/z
 answer
 A. tan Y= y/z
