Solve for x in the literal equation-19=xy +Z.

X =

x=(-19-Z)/y

Step-by-step explanation:

-19=xy+Z

-19-Z=xy

-19-Z/y=x

x= -19/y - z/y

Step-by-step explanation:

isolate the variable by subtracting z to both sides

the equation should now be -19 -z = xy

now divide y to the other side

you should be left with x=-19/y - z/y

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
