Question

Express Cos K as a fraction in the simplest terms.

Answer 1

The correct value of Cos K is 5/23

Step-by-step explanation:

In a right angle triangle, there are 3 side

1. Hypothenus (this is the longest)

2. Adjacent

3. Opposite

However, we can only determine the adjacent and opposite if an angle is marked in the triangle.

Now, we shall determine the value of Cos K. This can be obtaineasobtain as followed:

From the question given above, the following data were obtained:

Hypothenus = 23

Adjacent = 5

Cos K =? C

The value of Cos K can be obtained by using the cosine ratio as as illustrated below:

$Cos K =\frac{Adjacent}{Hypothenus}\\\\Cos K = \frac{5}{23}$

Therefore, the value of Cos K is 5/23
