Answer:

B) cos 55

Explanation:

Consider a right angle triangle with 35 angle, the other angle = 180 - 90 - 35 = 55

sin 35 = opposite side of 35 angle / hypothesis

Opposite side of 35 angle is the same as the adjacent side of 55 angle

sin 35 = adjacent side of 65 angle / hypothesis = cos 55

The answer is B.
