The C option is correct.
Angle is the space between the line or the surface that meets. And the angle is measured in degree. For complete 1 rotation, the angle is 360 degrees.
Given
∠1 is 61.8°
The ∠6 will be.
We know that when two lines parallel then the alternate angle are equal.
According to this ∠7 and ∠1 are the alternate angle.
∠7 = ∠1 = 61.8°
We know that line makes 180° itself. That is
∠6 + ∠7 = 180°
∠6 + 61.8° = 180°
∠6 = 180° - 61.8°
∠6 = 118.2°
Hence the ∠6 is 118.2°.
Thus, the C option is correct.
