Please help! And also with a detail explanation so I can solve the next one on my own !

Answer:
sin D = 0.25
Step-by-step explanation:
If ∠E = 90°, it means that the triangle is a right angle triangle.
Thus, hypotenuse will be the longest side which will be DC = 65
Since we are given CE = 16 and ED = 63, I have attached a diagram showing this triangle.
From the diagram, since we are looking for sin ∠D, we can say that;
sin D = opposite/hypotenuse
Now, opposite = CE = 16
Hypotenuse = CD = 65
Thus;
sin D = 16/65
sin D = 0.2462
Approximating to the nearest hundredth gives;
sin D = 0.25
