sin 85° = 0.9962
In the second quadrant, the values for sin are positive.
You can use formula:
sin ( 180° - θ ) = sin θ
sin ( 180° - 85° ) = sin 95° = sin 85° = 0.9962
In the third and fourth quadrants the values for sin are negative, so the only angles between 0°and 360° whose sine is 0.9962 are:
θ = 85° and θ = 95°
