Answer:

m ∠D = 17°

Step-by-step explanation:

The hypotenuse = 9

2.7 is on the side of the right triangle that is opposite the m ∠ D

Sin ∠D = opposite side/ hypotenuse

sin ∠D = 2.7/9        this problem will have to be worked by using  [tex]sin^{-1}[/tex]

                              [tex]sin^{-1}(2.7/9)[/tex] = 17.4576

∠D = 17°
