Answer 1

Answer:

HELLO

When a ray stands on a line, two adjacent angles are formed.

We know that the angle lying on a straight line is 180°.

The two angles being adjacent, make a total angle of 180° on the straight line.

Another way, we can see since the ray stands on the straight line, we can consider it is a perpendicular line.

Thus, the two adjacent angles are right angles.

So, the total angle

= 90° + 90°

= 180°
