one corner. The chest is 2 feet wide and 2 feet long. What is the
area of the rug that is not covered by the chest?

im trinna find out'

step-by-step explanation:

i am sure it will be 90 degrees.

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
