You can put this solution on YOUR website! Approximate, to the nearest 0.1°, all angles A in the interval [0°, 360°) that satisfy the equation. Separate your answers by commas.
(a) tanA = 3.8948
arctan(3.8948) = 75.60.. degrees or 255.60...degrees
-------------------------------------------------
(b) cot(A) = -0.9205
1/(-0.9205) = -1.086366...
arccot(A) = arctan(-1.086366) = 312.6296...degrees or 132.6296..
==================================
