The length of line segment AB as required to be determined in the task content is; 53/45.
<h3>What is the length of the line segment AB as required?</h3>
It follows from the task content that the length of the line segment AB is to be determined as required in the task content.
Since the point, S is a point on line segment AB such that;
AS = 7/9 and SB = 2/5
It follows that the required length of line segment AB is defined as the sum of the lengths of line segments AS and SB.
Therefore; AB = 7/9 + 2/5
AB = (35 + 18) / 45 = 53/45
Ultimately, the required length of line segment AB is; 53/45.
PS;
Also, Two angles are said to be supplementary if the sum of their measures is equal to 180°.
Therefore, since <B is supplementary to <A; the measure of <B is; 180° - <A.
