(a) The area of a rectangular garden is 8245 m m?
If the width of the garden is 85 m, what is its length?

98

Step-by-step explanation:

I got 98 on the calculator

< 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
