the missing side is 15.1
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
