The cost of a service call to fix a washing machine can be expressed by the linear function Y = 45x+35, where y represents th total cost and x represents the number of hours it takes to fix the machine. What does the y-intercept represent?

whats the real answer?

Step-by-step explanation:

< 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
