Explanation:

Step1: Recall sine - ratio formula

The sine of an angle in a right - triangle is defined as $\sin\theta=\frac{\text{opposite}}{\text{hypotenuse}}$. For $\sin Q$, the side opposite to angle $Q$ is $OP = 20$ and the hypotenuse is $OQ=25$.

Step2: Calculate $\sin Q$

$\sin Q=\frac{OP}{OQ}=\frac{20}{25}=\frac{4}{5} = 0.8$

Answer:

$0.8$
