Answer:Sin of ∠D = 39/89
Step-by-step explanation:
The diagram of the right angle DEF is shown in the attached photo.
To determine the ratio representing the sine of ∠D, we would apply the sine trigonometric ratio. It is expressed as
Sin# = opposite side/hypotenuse
Looking at the triangle
Opposite side = 39
Hypotenuse = 89
# = ∠D
Therefore
Sin of ∠D = 39/89
