The trigonometric ratio for cos C comes to be [tex]CosC =\frac{15}{17}[/tex].
What is the Cosine of an angle?
The cosine of an angle is the ratio of the adjacent side(to that angle) to the hypotenuse of that triangle.
In the given problem,
Adjacent side to the angle C = 45
The hypotenuse of the right-triangle = 51
[tex]Cos C = \frac{AdjacentSide}{Hypotenuse}[/tex]
So, [tex]Cos C = \frac{45}{51}[/tex]
[tex]CosC =\frac{15}{17}[/tex]
Therefore, the trigonometric ratio for cos C comes to be [tex]CosC =\frac{15}{17}[/tex].
