Question

If theta lies in 2nd quadrant then which is true:
a) 90°<theta/2<0°
b) 90°<=theta/2<=0°
c) 90°<theta/2<=0°
d) 90°<=theta/2<0°

(Here theta is an angle) ​

Answer 1

Answer:

none of the option is true

let theta is represented as angle a

as a lies in second quadrant

so 90 < a < 180

45 < a/2 < 90
