Explanation:

Step1: Recall cosine ratio formula

The cosine of an angle in a right - triangle is defined as $\cos\theta=\frac{\text{adjacent}}{\text{hypotenuse}}$. For angle $F$, the side adjacent to angle $F$ is $15$ and the hypotenuse is $25$.

Step2: Calculate the cosine value

$\cos F=\frac{15}{25}$

Step3: Simplify the fraction

$\frac{15\div5}{25\div5}=\frac{3}{5}$

Answer:

$\frac{3}{5}$
