What is the surface area of the cube? drag and drop the correct surface area to match the cube. cube with edge length = 3.2 m 12.8 m² 51.2 m²61.44 m²19.2 m²

answer: hi

step-by-step explanation:

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
