Answer: option D is correct
Explanation:
The given figure is a right angle triangle.
From the given right angle triangle,
the hypotenuse of the right angle triangle is 15
With 22° as the reference angle,
the adjacent side of the right angle triangle is the unknown side.
the opposite side of the right angle triangle is x.
To determine x, we would apply
the sine trigonometric ratio.
Sin θ, = opposite side/hypotenuse. Therefore,
Sin 22 = x/15
x = 15Sin22 = 15 × 0.3746
x = 5.6 to the nearest tenth.
