Force A, at 170 pounds, and force B, at 605 pounds, make an angle of 115° with each other. Represent their respective vectors as complex numbers written in trigonometric form and solve for the resultant angle to one decimal place.
A) Trigonometric form: 170(cos 0° + i sin 0°) + 605(cos 115° + i sin 115°) or 605(cos 0° + i sin 0°) + 170(cos 115° + i sin 115°)
B) Trigonometric form: 170(cos 0° + i sin 0°) + 605(cos 115° + i sin 115°)Resultant angle: 81.1°
C) Trigonometric form: 170(cos 115° + i sin 115°) + 605(cos 115° + i sin 115°)Resultant angle: 81.1°
D) Resultant angle: 81.1°
