cos(x)=(-4)/(8/3 sqrt(3))

cos (x) = \frac{- 4}{\frac{8}{3} 3}

x = \frac{5 π}{6} + 2 πn, x = \frac{7 π}{6} + 2 πn

Solution steps

cos (x) = \frac{- 4}{\frac{8}{3} 3}

Simplify

\frac{- 4}{\frac{8}{3} 3} : - \frac{3}{2}

General solutions for

cos (x) = - \frac{3}{2}

x = \frac{5 π}{6} + 2 πn, x = \frac{7 π}{6} + 2 πn

- 2 tan (x) + 6 = 8

2 sin (x) = 1.564

sin (x) = 0.08

sin (x) = 0.05

sin (x) = 0.21
