Trigonometric Ratios

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
