What is The vertex of the graph of f(x) = -0.75|x + 3|

(-3,0)

Step-by-step explanation:

Use desmos graphing calculator or look at x+3 and change the sign to a negative and that makes your vertex (-3,0)

< 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
