Step-by-step explanation:
= sec (360+120).cosec (360+80+30).tan(360-30)/sin (360+180+120).cos (360+180+120).cot (360+45)
= sec120. (-cosec30°). (-tan30°)/(-sin60°). (-cos120°). (cot45°)
= sec (90+30.cose30°.tan30°/sin60.cos (90+30).cot45°
= (-cosec) coec30°. tan30°/sin60°. (-sin30°).cot45°
= 2.2.1/root3/root3/2.1/2.1
