Question

3. If the initial ray and directed ray are
opposite rays, then directed angle formed
is called as
(A) Zero angle
(B) straight angle
(C) co-terminal angle
(D) standard angle​

sorry this is maths

Answer 1

Explanation:

1. If the initial ray and directed ray are opposite

rays, then directed angle formed is called as

(A) zero angle (B) straight angle

(C) co-terminal angle (D) standard angle

Answer 2

Answer:

The correct option is B.

Explanation:

An angle measuring zero degrees is called a zero angle. The angles having the same initial and terminal side are called co-terminal angles. It is obtained by adding or subtracting 360° to the given angle.

Standard angles are primary angles of trigonometry like 30° 40° 45° etc.

The angle formed by two opposite rays is  180° so it is called a straight line.

Hence option B is correct.
