The given triangle is a right triangle. We would determine Sinx and Cosy.
Taking angle x as the reference angle,
opposite side = 7
hypotenuse = 25
Recall, Sinθ = opposite side/hypotenuse
Thus,
Sinx = 7/25
Taking angle y as the reference angle,
adjacent side = 7
hypotenuse = 25
Recall, Cosθ = adjacent side/hypotenuse
Thus,
Cosx = 7/25
Thus, the correct option is
The ratios are both identical(7/25, 7/25)
