During the 2005-2006 term. 184 decisions were announced. This is a 44.6% decrease from the number of decisions announced during the 1982-1983 term. How many decisions were announced during 1982-1983? Round to the nearest whole number

332.

Step-by-step explanation:

Let the number of decisions made in 1982-1983 be x.

44.6% = 0.446.

This is a decrease,  so the number of decisions announced in 2005-2006 is

(1 - 0.446) * x and this =  184.

0.554x = 184

x = 184/0.554

x = 332.

< 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
