Answer:

B. 15/17

Explanation:

(see attached graphic for reference)

Because we have a right triangle (i.e one of the internal angles is 90 degrees), we can use trigonometry to solve

from the diagram, we can see that

cos 28° = adjacent length / hypotenuse

we can also see that the length adjacent to 28° = 15 units and the hypotenuse is 17 units,

hence, substituting these values into the equation:

cos 28° = 15 / 17 (answer)

edit: typo

Answer:


(15)/(17)

Option B is the correct option.

Here,

Adjacent=15

Hypotenuse=17

Now,


cos \: theta = (adjacent)/(hypotenuse) \\ cos \: 28 = (15)/(17)

Hope this helps..

Good luck on your assignment..
