Snezhnost [94]

Since it forms a "right triangle" we can apply trigonometry.
sin x = oppo/hyp
sin x = 13/20
x = sin^-1(13/20)
x = sin^-1(0.65)
x = 40.5
rounded to nearest degree
x = 41 degrees

$y\:$

The blue boundary line passes through the origin and has slope $-1$ .

Its equation is $y=-x.$

Since the boundary line is not solid and the right half-plane is shaded, its inequality is $y\:>\:-x$

The correct choice is D.
