1/5 x -12

Will give Brainliest if correct!

-9

Step-by-step explanation:

Plug in 15 for x in the equation

you should get (1/5*15) -12

multiply 1/5 and 15 to get 3

then 3-12=-9

therefore the answer is -9

7

step-by-step explanation:

yuo ned the activity or vertical angle of the form of 1,7 but 2,2 has a c4,2 as it verticie so i not have a car

< 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
