cos(x)= 4/8

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

x = \frac{π}{3} + 2 πn, x = \frac{5 π}{3} + 2 πn

Solution steps

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

Cancel the common factor:

4

cos (x) = \frac{1}{2}

General solutions for

cos (x) = \frac{1}{2}

x = \frac{π}{3} + 2 πn, x = \frac{5 π}{3} + 2 πn

\frac{sin ( 5 1 ^{\circ} )}{18} = \frac{sin ( x )}{22}

3 (1 + sin (θ)) = 3 (1 - sin (θ))

cos (2 x) = sin (7 0^{\circ} + x)

tan (3 x) \cdot cot (x + 4 0^{\circ}) = 1

2 cos (θ) + 53 = 43
