2 x + 60 = 3 0^{\circ} + 36 0^{\circ} n, 2 x + 60 = 15 0^{\circ} + 36 0^{\circ} n

2 x + 60 = 3 0^{\circ} + 36 0^{\circ} n, 2 x + 60 = 15 0^{\circ} + 36 0^{\circ} n

Solve

2 x + 60 = 3 0^{\circ} + 36 0^{\circ} n : x = - 30 + 18 0^{\circ} n + 1 5^{\circ}

2 x + 60 = 3 0^{\circ} + 36 0^{\circ} n

Move

60

to the right side

2 x + 60 = 3 0^{\circ} + 36 0^{\circ} n

60

from both sides

2 x + 60 - 60 = 3 0^{\circ} + 36 0^{\circ} n - 60

Simplify

2 x = 3 0^{\circ} + 36 0^{\circ} n - 60

2 x = 3 0^{\circ} + 36 0^{\circ} n - 60

Divide both sides by

2

2 x = 3 0^{\circ} + 36 0^{\circ} n - 60

Divide both sides by
