Find sec x if sin x = -0.6 and cos x = 0.8.
is sinx = - and cosx = +, then x must be in IV
cosx = .8 = 8/10 = 4/5
since secx = 1/cosx
secx = 1/(.8) = 5/4
To find the value of sec x given sin x = -0.6 and cos x = 0.8, we can use the equation sec x = 1/cos x.
We are given that cos x = 0.8.
Using the equation sec x = 1/cos x, we can substitute the value of cos x into the equation:
sec x = 1/0.8
To calculate sec x, divide 1 by 0.8:
sec x ≈ 1.25
Therefore, the value of sec x is approximately 1.25.
