The answer to your question is: 45° and 225°
Step-by-step explanation:
Getting tan⁻¹ 1 = 45°
Then, the angle we are looking for is 45°, let's check the for quadrangles.
First quadrangle = tan 45 = 1
Second quadrangle = 180° - 45° = 135° tan 135 = -1
Third quadrangle = 180 + 45 = 225° tan 225 = 1
Forth quadrangle = 360 - 45 = 315° tan 315° = -1
