Cos A 4/5 so the answer is d

Step-by-step explanation:

D

Step-by-step explanation:

Remark

The tangent is described as the ratio of the side opposite the reference angle divided by the side adjacent to the reference angle.

In this case

The reference angle is B

The side opposite is AC and it has a value of 4

The side adjacent is BC and it has a value of 3

Hypotenuse

If you are finding either the sine or cosine of any angle, you need the hypotenuse.

AB^2 = 4^2 + 3^2 = 16 + 9

AB^2 = 16 + 9

AB^2 = 25

Take the square root of 25

AB = 5

Cos(A)

The cos(A) = adjacent / hypotenuse

Adjacent = AC = 4

Hypotenuse = AB = 5

Cos(A) = a/h

Cos(A) = 4/5 which is D

if this is really you s much. i only have 3 points left and i have 2 questions to ask

i'm sorry i don't know
