Answer:
5). x = 11.9°
6). x = 27.2°
Step-by-step explanation:
5). By applying cosine rule in the given triangle,
cos(32)° = 
cos(32)° = 
x = 14cos(32)°
x = 11.87
x ≈ 11.9°
6). By applying sine rule in the given triangle,
sin(54°) = 
sin(54°) = 
x = 
x = 27.19°
x ≈ 27.2°
A, $1.42. i found this answer plugging in 1.42 and seeing if it would work or not
#1 is irrational.
The other four are all rational.
