As shown in the figure, the known angle AOB = 90 degrees, the angle AOC is the acute angle. Od bisecting angle AOC, OE bisecting angle BOC. Calculate the degree of the angle doe? When the angle AOB = m degrees, the angle doe? Degree

Because: od bisection ∠ AOC,
So: ∠ AOD = ∠ doc,
Because: OE divides BOC equally,
So: ∠ COE = ∠ EOB,:
Because: ∠ doc + ∠ COE + ∠ AOD + ∠ EOB = 90 °
So: ∠ DOE = ∠ doc + ∠ COE = 45 °
When ∠ AOB = m degree,
∠DOE=m°/2.
