Answer:

Y = 59.0°

Step-by-step explanation:

Using the cosine rule in terms of x, y and z

cosY = \frac{x^2+z^2-y^2}{2xz}

with x = 22, y = 20 and z = 18

cosY = \frac{22^2+18^2-20^2}{2(22)(18)}

        = \frac{484+324-400}{792}

        = \frac{408}{792}, thus

Y = cos^{-1} (\frac{408}{792} ) ≈ 59.0° ( to the nearest tenth )
