Apply distributive property to create an equivalent expression 6(5r-3)=

30r-18

Step-by-step explanation:

6*5=30

6*3=18

step-by-step explanation:

subtract 7, so the answer is x < = 3, or c.

< 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
