Under her cell phone plan, Myesha pays a flat cost of $35 per month and $5 per gigabyte. She wants to keep her bill under $55 per month. Write and solve an
inequality which can be used to determine g, the number of gigabytes Myesha can
use while staying within her budget.

< 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
