When Owen left his house in the morning, his cell phone battery was partially charged. Let B represent the charge remaining in Owen's battery, as a percentage, t
hours since Owen left his house. A graph of B is shown below. Write an equation for
B then state the x-intercept of the graph and determine its interpretation in the
context of the problem.

your answer is a

step-by-step explanation:

plzplzplzplzplz mark brainliest i need it.

< 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
