Given the system of equations, what is the value of x + y?
x + 2y = 24
2x + y = 9

b

step-by-step explanation:

hope this .

r3t40

step-by-step explanation:

a rhombus is a parallelogram enjoying his symmetry.

< 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
