a) \(\sin x = 0,2368;\)
Ta có: \(\sin x = 0,2368\) nên \(x = {13^0}41'51,9'' \approx {13^0}42'\)
b) \(\cos x = 0,6224;\)
Ta có: \(\cos x = 0,6224\) nên \(x = {51^0}30'30,21'' \approx {51^0}31'\)
c) \(\tan x = 1,236;\)
Ta có: \(\tan x = 1,236\) nên \(x = {51^0}1'30,04'' \approx {51^0}2'\)
d) \(\cot x = 2,154.\)
Ta có: \(\cot x = 2,154\) nên \(x = {24^0}54'11,54'' \approx {24^0}54'\)
