hint: we can write this: \(\tan(180)=\sin(180)/\cos(180)=...?\)

You might want to draw the angle 180 deg. Can you then identify the "opposite side," the "adjacent side," and the "hypotenuse?"

I agree with Michele Laino's re-writing of tan 180, but would like to point out that tan 180 = (opposite side) / (adjacent side).

Using the "unit circle" here is fine, but not essential.
