Answer: Option 'B' is correct.
Step-by-step explanation:
Since we have given that
The tangent of an angle is defined as the ratio of opposite side to adjacent side.
Mathematically, it is expressed as
[tex]\tan \theta=\dfrac{Perpendicular}{Base}[/tex]
where, Perpendicular is the opposite side of theta Ф.
and base is the adjacent side of theta Ф.
So, it is ratio and ratio is a type of fraction and it is read as opposite overt adjacent.
But it is not a proportion.
Hence, Option 'B' is correct.
