Answer: Hence, the value of
$(\cos A)/(\cos B)=(0.7)/(0.7)$ is 1.

Explanation:

Since we have given that

ABC is a right angled triangle.

We need to find the value of
$(\cos A)/(\cos B)$

As we know the formula for "Cosine Rule ":

$\cos A=(Adjacent\ side\ to\ A)/(Hypotenuse)\\\\\cos A=(3)/(4.24)=0.7$

similarly,

$\cos B=(Adjacent\ side\ to\ B)/(Hypotenuse)\\\\\cos B=(3)/(4.24)=0.7$

So,
$(\cos A)/(\cos B)=(0.7)/(0.7)=1$

Hence, the value is 1.
