<span>(a.)
Let's say α is the angle that subtends from the top of the screen to horizontal eye-level.
Let β be the angle that subtends from the bottom of the screen to horizontal eye-level.
tanα = (22 + 10 - 4) / x = 28/x
α = arctan(28/x)
tanβ = (10 - 4) / x = 6/x
β = arctan(6/x)
Ɵ = α - β
Ɵ = arctan(28/x) - arctan(6/x)
(b.)
tanƟ = tan(α - β) = (tanα - tanβ) / (1 + tanα tanβ)
tanƟ = (28/x - 6/x) / [1 + (28/x)(6/x)]
tanƟ = (22/x) / [1 + (168/x²)]
tanƟ = 22x / (x² + 168)
Ɵ = arctan[22x / (x² + 168)]</span>

Let's check the answer:
Answer:
C
Step-by-step explanation:
By the definition of negative indices, we can rewrite our expression:
And by the definition of fraction powers, we can rewrite our term:
![\frac{1}{y^-^\frac{4}{3} }=\frac{1}{(\sqrt[3]{y})^4}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7By%5E-%5E%5Cfrac%7B4%7D%7B3%7D%20%7D%3D%5Cfrac%7B1%7D%7B%28%5Csqrt%5B3%5D%7By%7D%29%5E4%7D)
Not sure if that's what C says because the picture is kinda blurry.
