Answer 1

Answer: $\frac{cosA}{cosB}=1$

Step-by-step explanation:

By definition you have that:

$cos\alpha=\frac{adjacent}{hypotenuse}$

Then:

$cosA=\frac{3}{4.24}$

and

$cosB=\frac{3}{4.24}$

As you can see, cosA and cosB are equal, therefore you can conclude its division is 1, therefore:

$\frac{cosA}{cosB}=1$

Answer 2

Answer:

The correct answer is CosA/ Cos B = 1

Step-by-step explanation:

Cos ∅ = Adjacent side/Hypotenuse

Hypotenuse = 4.24

From the figure we can see that, a right angled triangle

To find Cos A

Adjacent side of angle A = 3

Cos A = Adjacent side/Hypotenuse = 3/4.24

To find Cos B  

Adjacent side of angle B = 3

Cos B = Adjacent side/Hypotenuse = 3/4.24

To find CosA/ Cos B

CosA = 3/4.24

Cos B =  3/4.24

CosA/ Cos B = (3/4.24)/(3/4.24) = 1
