The sine ratio of angle θ from the given triangle is; 4/5
The triangle is missing and so i have attached it.
We know that trigonometric ratios is as follows;
sin θ = opposite/hypotenuse
cos θ = adjacent/hypotenuse
tan θ = opposite/adjacent
From the attached triangle, we see that;
Opposite = 4
Hypotenuse = 5
Thus;
sin θ = 4/5
