∴

θ pr = a \tan (\frac{\sqrt{({30.01m/s}^{2} \cdot {(\sin (44.99°))}^{2}) - 2 \cdot 9.8066m/s² \cdot 11.5m}}{30.01m/s \cdot \cos (44.99°)})

Next Step Convert Units

∴

θ pr = a \tan (\frac{\sqrt{({30.01m/s}^{2} \cdot {(\sin (0.7852rad))}^{2}) - 2 \cdot 9.8066m/s² \cdot 11.5m}}{30.01m/s \cdot \cos (0.7852rad)})

Next Step Prepare to Evaluate

∴

θ pr = a \tan (\frac{\sqrt{({30.01}^{2} \cdot {(\sin (0.7852))}^{2}) - 2 \cdot 9.8066 \cdot 11.5}}{30.01 \cdot \cos (0.7852)})

Next Step Evaluate

∴

θ pr = 0.614810515101847rad

Next Step Convert to Output's Unit

∴

θ pr = 35.2260477156066°

LAST Step Rounding Answer

∴

θ pr = 35.226°
