The length of the side with length of y is; 51.32
How to use Trigonometric Ratios?
From the given triangle, we can say that the side with length of 35 is the adjacent side if we are considering the angle 47°.
From trigonometric ratios, we know that;
Adjacent/Hypotenuse = cos θ
Thus;
35/y = cos 47
35/y = 0.682
y = 35/0.682
y = 51.32
