An angle of depression involves you at a point and looking downward, with your eyes as the vertex. (An angle of elevation goes up from your line of sight.)
In the picture, imagine your eyes are point A. To make an angle of depression, you look downward. The angle made is angle #1, as none of the other angles use A as a vertex.
Answer:
C
Step-by-step explanation:
we know that
In a right triangle
The cosine of an angle x is equal to
cos(x)=\frac{adjacent\ side\ angle\ x}{hypotenuse}
The sine of an angle x is equal to
sine(x)=\frac{opposite\ side\ angle\ x}{hypotenuse}
The tangent of an angle x is equal to
tan(x)=\frac{opposite\ side\ angle\ x}{adjacent\ side\ angle\ x}
therefore
the answer is the option C
