Jessica completed a race last week. she swan, biked and ran. how many miles did she complete? swan 400 meters, biked 10 kilometers, ran 1.5 kilometers

7.1482542 Miles

Step-by-step explanation:

I got this by changing 400 meters to kilometers 400 meters=0.004 kilometers

Then added 0.004+10+1.5=11.504 Last I did 11.504 kilometers and changed it to miles which is 7.1482542 Miles.

< 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
