\frac{3 x}{2} + 4 5^{\circ} = 0 + 36 0^{\circ} n, \frac{3 x}{2} + 4 5^{\circ} = 18 0^{\circ} + 36 0^{\circ} n

\frac{3 x}{2} + 4 5^{\circ} = 0 + 36 0^{\circ} n, \frac{3 x}{2} + 4 5^{\circ} = 18 0^{\circ} + 36 0^{\circ} n

Solve

\frac{3 x}{2} + 4 5^{\circ} = 0 + 36 0^{\circ} n : x = \frac{72 0 ^{\circ} n}{3} - 3 0^{\circ}

\frac{3 x}{2} + 4 5^{\circ} = 0 + 36 0^{\circ} n
