Check my answer? ? find the distance between the points a(10, –9) and b(8, 7). round your answer to the nearest hundredth.
a.5.09
b.10.63
c.15.00
d.16.12

x = -2

y = 848

step-by-step explanation:

plug in the numbers

< 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
