Answer:
B) cos 55
Step-by-step 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.
