Answer 1

An angle bisector divides the angle in half. For your first problem, it shows you that angle SQR is 22 degrees. This means the other half must be 22 degrees (angle PQS). Adding the two angles together gives you the angle of the whole (angle PQR), which is 44 degrees.

Just remember that the angle bisector simply divides an angle into equal halves.
