Determine the measure of A if 0 degrees is less or equal to angle A and if angle A is less or equal to 360 degrees.

Tan A = 0

Answer is somehow supposed to be 0 degrees, 180 degrees, and 360 degrees, but don't know how to get the answer, just really confused.

Sin A = -1

In your text you should have the graphs of the

sine, cosine and tangent curves.

Take a look where the tangent curve cuts the x-axis in the given domain

for the second, look at the sine curve,

when is it at -1, its lowest value.
