Wi marr brainliest! answer ! the bar graph shows the number of hurricanes in the atlantic basin from 2006 - 2011. between which two years was the percent change the greatest? what was the percent of change during the period.

< 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
