TSW = 1.5 t
t + 1.5t + 2t = 180
4.5 t = 180
t = 40
2t = WSR = 80

Method 1: From the diagram; \(∠TSR + t° = 180°\)
Given; \(∠TSR = 3.5t°\)
\(3.5t° + t° = 180 = > 4.5t° = 180\)
\(t° = \frac{180}{4.5} = 40°\)
\(∠WSR = 2t° = 2*40 = 80°\)
Method 2: \(∠TSR = ∠TSW + ∠WSR\)
\(∠TSR = 3.5t°\)
\(∠WSR = 2t°\)
\(∠TSW = 3.5t° - 2t° = 1.5t°\)
\(t° + 1.5t° + 2t° = 180°\)
\(4.5t° = 180°\)
\(t° = \frac{180}{4.5} = 40°\)
\(∠WSR = 2t° = 2*40 = 80°\)
Answer (E)...
