A root of the equation

\sin x+x-1=0

lies in the interval

View answer and explanation

Correct option: A

\left(0, \frac{\pi}{2}\right)

Option A

\left(0, \frac{\pi}{2}\right)

is correct because the equation

\sin x + x - 1 = 0

has a root in this interval, which can be seen by observing the behavior of the function at the interval's endpoints.
