Use the unit circle to find the value of tan (-180º).

B. tan (-180°) = 0

Step-by-step explanation:

Tangent is the ratio of opposite to adjacent to an angle

From the unit circle; the opposite to our angle -180° is 0

The adjacent along the x-axis is 1

Therefore;

Tan (-180°) = 0/1

              = 0

Therefore; Tan (-180°) is 0

on a coordinate grid, point a is at (−4.0, −2.4) and point b is at (4.0, −2.4). point b is a reflection of point a across the –axis. input either a lowercase x or i think is the right awnser
