Explanation:

Step1: Recall sine ratio formula

The sine of an angle in a right - triangle is defined as $\sin\theta=\frac{\text{opposite}}{\text{hypotenuse}}$. In right - triangle $DEF$ with right - angle at $E$, for $\angle D$, the side opposite $\angle D$ is $EF = 5$ and the hypotenuse is $DF=7$.

Step2: Calculate $\sin D$

$\sin D=\frac{EF}{DF}=\frac{5}{7}\approx0.71$

Answer:

$0.71$
