perimeter = 26 m

for area ,divide figure in two parts

area = area of 1st part = 8 m^2

area of 2nd part = 7m^2

area of whole figure = 15m^2

hope it helps

< 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
