If a ray stands on a line then the sum of the adjacent angle so formed is ?

Open in App

Solution

Find the sum of adjacent angles based on given information
Given, a straight line
We know, the angle on a straight line is $180^{\circ}$
Ray $O B$ creates two adjacent angles on a line, $∠ C O B$ and $∠ A O B$ .
So, sum of these two adjacent angles is
$∠ C O B + ∠ A O B = 180^{\circ}$
Hence, sum of the adjacent angle on a line is $180^{\circ}$ .
