Cameron has 480 stamps. 5/8 of them are U. S. stamps and the rest are foreign stamps. How many more U. S. stamps than foreign stamps does he have?

120

Step-by-step explanation:

US stamps = 5/8 × 480

= 300

foreign stamps = 480- 300

= 180

more US stamps than foreign stamps = 300-180

= 120

i would say c is the best answer, hope it's right!

good luck! =)

< 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
