If y=-4 when x=8, find x when y=-2

4

Step-by-step explanation:

find the stuff the answers is four

if y=4 is x=8 then it’s multiplied by 2 you see so y=2 times 2 is 4 so the answe is x=4

< 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
