Best Answer

sec(x)= -1.834

Using the inverse secant, we have that :

sec^-1 (-1.834) = theta ≈ 123.042°

The other value between 0 and 360 is 180 + (180 - 123.042) ≈ 236.958°

Since sec = 1/cos, sec(x) = 1.834 ---> cos(x) = 1/1.834 ---> cos(x) = 0.545

---> x = cos^-1(0.545) = 57^o (approx)

Since cos(360^o - x) = cos(x), x could equal 360^o - 57^o = 303^o.
