Angle of Emergence Solution

Follow our step by step solution on how to calculate Angle of Emergence?

FIRST Step Consider the formula

e = A + D - i

Next Step Substitute values of Variables

∴

e = 35° + 9° - 40°

Next Step Convert Units

∴

e = 0.6109rad + 0.1571rad - 0.6981rad

Next Step Prepare to Evaluate

∴

e = 0.6109 + 0.1571 - 0.6981

Next Step Evaluate

∴

e = 0.06981317007976rad

Next Step Convert to Output's Unit

∴

e = 3.99999999999999°

LAST Step Rounding Answer

∴

e = 4°
