If 0<x<π20 < x < \frac{\pi }{2}, then the largest angle of a triangle whose sides are 1,sin⁡x,cos⁡x1,\sin x,\cos x is
View answer and explanation
Correct option: B
π2\frac{\pi }{2}
Option B (π2\frac{\pi }{2}) is correct because since 0<sin⁡x<10 < \sin x < 1 and 0<cos⁡x<10 < \cos x < 1, the side with length 1 is the largest, and the angle opposite to it is a right angle.
