Given the angle


-(5\pi)/(4)

Add 2π to the angle to find the corresponding positive angle

so, the angle will be:


-(5\pi)/(4)+2\pi=(3\pi)/(4)

So, the angle Lies in the second quadrant

so, the reference angle will be:


\pi-(3\pi)/(4)=(\pi)/(4)

so, the answer will be the reference angle = π/4
