By definition, an angle bisector is a ray that divides an angle into two congruent angles.
In our question we have been given that GJ is the ray that is the angle bisector and that has been shown in the diagram.
Now, since, , therefore, the ray
will divide the original angle
into two congruent angles,
and
. Since, the division is equal, the values of both these angles will be half of the original angle. Thus, we will have:
Thus, the required value of
