Answer 1

The correct answer is CosA/ Cos B = 1

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

Answer 2

Answer:
`(cosA)/(cosB)=1`

Explanation:

By definition you have that:

`cos\alpha=(adjacent)/(hypotenuse)`

Then:

`cosA=(3)/(4.24)`

and

`cosB=(3)/(4.24)`

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

`(cosA)/(cosB)=1`
