Given:
In the given circle O, BC is diameter, OA is radius, DC is a chord parallel to chord BA and 
.
To find:
The 
.
Solution:
If a transversal line intersect two parallel lines, then the alternate interior angles are congruent.
We have, DC is parallel to BA and BC is the transversal line.
[Alternate interior angles]
In triangle AOB, OA and OB are radii of the circle O. It means OA=OB and triangle AOB is an isosceles triangle.
We know that base angles of an isosceles triangle are congruent.
[Base angles of an isosceles triangle]
In triangle AOB,
Therefore, the measure of angle AOB is 120 degrees.

Answer:
Find out the what is the salesman's commission as a percent of his total monthly sales .
To prove
Formula
As given
A car salesman had $65,100 in total monthly sales last month. He made $1,953 in commission from those sales.
Here
Part value = $1953
Total value = $ 65100
Put in the formula
Percentage = 3%
Therefore the salesman's commission as a percent of his total monthly sales is 3% .
