Aclothing company makes a profit of 2.3 million. this is 4.1 million more than last year .what was the profit last year

$1.8 I thinkidk

Step-by-step explanation:

Let x represent what they made last year, in millions of dollars.

 x + 4.1 = 2.3

Solve for x by subtracting 4.1 from both sides. It looks like they lost $1.8 last year.

< 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
