Answer:
Step-by-step explanation:
From the given right angle triangle,
The hypotenuse of the right angle triangle is x
With ∠33 as the reference angle,
The adjacent side of the right angle triangle is 15
The unknown side is the opposite side of the right angle triangle.
To determine x, we would apply
the cosine trigonometric ratio.
Cos θ, = adjacent side/hypotenuse. Therefore,
Cos 33 = 15/x
x = 15/Cos 33 = 15/0.839
x = 17.9 to the nearest tenth
