Answer:

The correct option is C.

Explanation:

Given information: In DEF, sin D= 36/39.

In a right angled triangle,

$\sin \theta=(perpendicular)/(hypotenuse)$

$\sin D=(EF)/(DE)$

(36)/(39)=(EF)/(39)

EF=36

$\cos \theta=(base)/(hypotenuse)$

$\cos E=(EF)/(DE)$

$\cos E=(36)/(39)$

The value of cos E is
(36)/(39) . Therefore the correct option is C.
