the missing side is 15.1

Step-by-step explanation:

angle = 57 degrees

opposite = side opposite the angle = x

hypotenuse = 18

Since we know the hypotenuse and we are looking for the opposite side, we would apply sine ratio:

sin 57 = opposite/hypotenuse

sin 57 = x/18

18(sin 57) = x

x = 18(0.8387)

x = 15.096

To the nearest tenth, the missing side is 15.1
