You first divide the number by 100 and then multiply it by the percentage that you are given
Answer:
- 2nd quadrant: 120°
- 3rd quadrant: 240°
Step-by-step explanation:
Dividing by cos(x)², you get
... (sin(x)/cos(x))² = 3
... tan(x)² = 3
... tan(x) = ±√3
... x = arctan(±√3) = ±60° + k·180° for any integer k
In the 2nd quadrant, ...
... x = 180° -60° = 120°
In the 3rd quadrant, ...
... x = 180° +60° = 240°
