what is the measure of angle a + angle b + angle c + angle d + angle e + angle f in the figure?

Definition - When two straight lines meet at a point they form an angle. The point at which the arms meet (O) is known as the vertex of the angle. The amount of turning from one arm (OA) to other (OB) is called the measure of the angle ( AOB) and written as m..
