$81.6
Step-by-step explanation:
You multiply 0.2 by 68, in which you will get 13.6, and then you add that to 68.
c ≈ 16.7 ( to 1 dec. place ) → d
since triangle ABC is right use the cosine ratio to find c
cos33° =
= 
multiply both sides by c
c × cos33° = 14 ( divide both sides by cos33° )
x =
≈ 16.7 ( to 1 dec. place )
