The sine function is symmetrical about 90*, so first-quadrant values are reflected across the y-axis into the 2nd quadrant.
θ = arcsin(0.4461857) ≈ 26.49922° . . . or . . . 153.50078°
26.49922, 153.50078

As you can see, a Google search box can tell you the answer. Your calculator can, too.
153.5° = 180° - 26.5° . . . . . . subtract the smaller angle from 180° to find the larger
