If cos (π + x) = 3 / 5, X ∈ (π, 2 π), then TaNx is equal to I want the process! Why cos (π + x) = 3 / 5, that is - cos x = 3 / 5? How to use x ∈ (π, 2 π)?

Cos (π + x) = - cosx cos (π + x) = 3 / 5 = 3 / 5 - cosx = 3 / 5 find TaNx TaNx = SiNx / cosx sin ^ 2x + cos ^ 2x = 1 x ∈ (π, 2 π) to show that SiNx is negative



TaNx ° = 8 / 6, how many degrees is x equal to


53 degrees. This is a common, 3,4,5 Pythagorean triangle



TaNx = 2 / 3, then how many degrees is x equal to


X = 33.69 degrees
