cos(x)=(5sqrt(2))/(10)

cos (x) = \frac{5 2}{10}

x = \frac{π}{4} + 2 πn, x = \frac{7 π}{4} + 2 πn

Solution steps

cos (x) = \frac{5 2}{10}

Cancel the common factor:

5

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

General solutions for

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

x = \frac{π}{4} + 2 πn, x = \frac{7 π}{4} + 2 πn

4 tan (x) + 4 = 0

4 sin (θ) - 3 = 0, 0 \leq θ \leq 2 π

x, 0 = - 5 sin (2 x)

1.2 sin (2 4^{\circ}) = 1.2 sin (x)

cos (C) = 20.09 - \frac{27.1441}{19.6}
