$$\left| cosx \right|\le1$$

Vocaloid · Answer

Keep in mind it says cosX 0 = (2 and 5 tenths) / (5 and 59 hundredths) not just 2

Sansthecomic · Answer

calculate the sum I think then subtract...Maybe

surjithayer · Answer

$$\cos x=\frac{ 2.5 }{5.59 }$$
only thing we can say is 
$$\cos~A=\frac{ 2.5 }{ 5.59}$$
