Answer:
103
Explanation:
How would we know what you don't care for. We can't read your mind...
Visualize the triangle or draw it out.
The angle bisector means that the angle or side is split in half.
Draw a straight line splitting the angle in half and heading out on both A and B.
As the question said, it should intersect once somewhere.
That angle formed by the intersection is <m and you want the measurement.
If the angles are bisected, the degrees must be halfed.
You half the two angles.
You add the two angles.
There are 180 degrees in a triangle, so you subtract it from 180.
There you go.
