132∠73度+176∠163度+352∠-17度
=132×cos73°+i132×sin73°+176×cos163°+i176×sin163°+352×cos(-17°)+i352×sin(-17°)
=38.593+i126.232-168.31+i51.457+336.619-i102.915
=206.903+i74.775
=220∠19.87°
=132×cos73°+i132×sin73°+176×cos163°+i176×sin163°+352×cos(-17°)+i352×sin(-17°)
=38.593+i126.232-168.31+i51.457+336.619-i102.915
=206.903+i74.775
=220∠19.87°
