Why might you need to use the addition or subtraction property of equality more than once after you have used the distributive property and combined like terms? explain.

horizontal translation of 2 units in the positive x direction

followed by

vertical translation of 3 units in the positive y direction

< 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
