If x=5 and y=7 find the value of x(y-2)

i need help

7-2=5  then 5 times 5 is 25 25 is the answer

Step-by-step explanation:

25

Step-by-step explanation:

5(7-2)

x(y-2)

35-10=25

< 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
