Given:
A figure.
To find:
The angle number which is supplementary to ∠OKL.
Solution:
The angles which lie on the same side of a straight line and their sum is 180 degrees, then they are called supplementary angles.
From the given figure it is clear that ∠OKL is lies on the intersection point K of lines OJ and GL.
[tex]\angle OKL=\angle 12[/tex]
Angle 11 and angle 12 lie on the same side of the straight line GL.
So, angle 11 and angle 12 are supplementary angles.
Therefore, angle 11 is supplementary to ∠OKL.
