Answer:
11). x = 25.8°
12). x = 67.3°
Step-by-step explanation:
11). By using sine rule in the given triangle,
    cos(x) = 
    cos(x) = 
    x = 
    x = 25.84
    x ≈ 25.8°
12). By applying tangent rule in the given triangle,
     tan(x) = 
     tan(x) = 
     x = 
     x = 67.29°
     x ≈ 67.3°
