Answer:
cos x° = 11 divided by k
Explanation:
Basic trigonometric identities are connected through a simple equation; tan x°=sin x°/cos x°, or speaking in letters: tangent of an angle is equal to the sine of that angle divided by the cosine of the same angle. So, in this case:
sin x° = j/k
tan x° = j/11
cos x° =?
Since tan x° = sin x°/cos x° that means that cos x° = sin x°/ tan x°
cos x° = j/k divided by j/11 which is equal to 11/k.
